Make sure you join this telegram group : @Tcsexplores  , as there are 1000s of TCS and Infosys software engineers who guides students regarding interview preparation and joining procedure . :) 

 

I will mention the preparation strategy and you guys mention the interview experiences !!!! 

SE -> Software Engineer (3.6 LPA)
SES - > Software Engineer Specialist (5LPA)
PP -> Power Programmer (8LPA)

This post is divided into 3 parts -

1 . Core CS Subjects

For all of three u have to prepare core cs subjects like CN , OS , DBMS , Computer Architecture Basics, OOPS , but how?

  • Resources for OOPS (c++ , Python , Java )

    This is very common they ask u on the basis of language u written in Resume.

    1. LINK1 2.1k [common]
    2. LINK2 1.2k[c++]
    3. LINK3 1.0k[ JAVA , (If u r sure then only write ) ]
    4. LINK4 1.2k[Python]

`

`

`

`

  • Resources for OS

    This subject is also important they ask very few questions (rarely to SE) but high chances for PP.

    1. Mutex VS Semaphores , Deadlock (Most common)
    2. LINK 921
    3. LINK 425
    4. LINK 341

`

`

`

`

  • Resources for Computer Architecture

    They ask very few questions for PP role (rarely for SE and SES )

    1. What are Flip-Flops?(Most common, may be asked for all)
    2. LINK 171
    3. Revise Cache memory , pipelining etc.

`

`

  • Resources for Software Engineering

    They ask at least a question from this.

    1. All software development models and cycles.
    2. LINK 685

2 . Coding / DSA

  • For SE

    For SE they ask very common questions.

    1. Prime Number , GCD
    2. Reverse a Number
    3. Reverse a string
    4. Bubble Sorting
    5. Reverse array
    6. Fibonacci
    7. Factorial of a number , and so on ( basically I gave u some rough idea)
  • For SES

    For SES they ask medium questions (included above too)

    1. Prime Number (Sieve)
    2. Pattern Printing
    3. Fibonacci (without recursion)
    4. Factorial (Without recursion)
    5. Max contiguous subarray sum
    6. Merge, Quick and Insertion Sort
    7. BFS / DFS
  • For PP

    For PP they ask some advanced question too (included above too)

    1. Revise all traversals ( Zigzag, In, pre , post , level etc)
    2. Sum of all subarray of an array
    3. Reverse linked list
    4. Find whether a loop in linked list
    5. Find whether there is a cycle in graph
    6. Implement AVL tree.
    7. Coin change problem.
    8. Heap Sort
    9. Graph coloring Problem
    10. shortest path in graph ( if u don’t know implementation just tell them thoery , Prim’s and Kruskal)
    11. Insertion and deletion in BST ( U have to write code)
    12. All views of the Binary search tree.
    13. Knapsack Problem
    14. Water Trapping Problem

I gave u some basic idea and some questions they asked the previous year . (google all above)

  2. LINK 227 [GFG - Infosys experience and Questions]
  3. LINK 259 [ Leetcode Top Interrview Questions]

3 . Resume / Projects / HR questions

  • Common Tips for all -

    1. Prepare your project very well, If u do not have a project I would suggest preparing a small project in this time duration remaining.
    2. Prepare your resume, go through it, and write only those things which u really know.
    3. Prepare all basics HR questions, like , why we hire you? blah blah.
    4. If u r disagree at some point be polite, and be confident, don’t be arrogant, sad, overexcited … a smiley face is sufficient.

Hope my above article helps u to clear the interview process (SE , SES , PP ) . 
Till then Practice fking hard, Because -

 When u r not practicing someone else is ,
 and the day you meet them u will lose.

PS : If someone read who also part of previous hack with infy can share their experience below in the comments. If u have any doubt let me know, If i m able to solve I will surely help 

EDIT : After the guidelines of infosys regarding interview two topics also added -

  1. Artificial Intelligence [ LINK1 221 , LINK2 40 , LINK3 21 , LINK4 19 ]

  2. Web Development [ LINK1 285 , LINK2 79 , LINK3 45]

Make sure you join this telegram group : @Tcsexplores  , as there are 1000s of TCS and Infosys software engineers who guides students regarding interview preparation and joining procedure . :) 

Round 1: Online based exam conducted at home where the exam had MCQs based on Data Structure and Algorithm, Basics of Java, and output problems. I cleared the first round and got a mail to attend the 2nd round in Heritage Institute of Technology, Kolkata.

Round 2: On 6th March(before lockdown), Online based exam was conducted in the center which had 2 sections.

  • 1st Section had 20 MCQs based on DBMS (SQL), OOPs (Python/Java), and Data Structures and Algorithms. 
  • 2nd Section had 2 Coding questions to be solved in Java/Python and Coding questions were on Intermediate level with String and Array-based problems.

After completing Round 2, I had to wait for 2 hours in the center for the results. Then they announced the name of shortlisted students for HR interview.

 

 

 

Round 3: HR interview with Infosys Talent Acquisition team:

  1. Introduce yourself.
  2. What is the meaning of your name?
  3. Explain your projects.
  4. What are your strength and weaknesses?
  5. How do you face your weaknesses?
  6. Are you willing to relocate?
  7. What do you do in your off time?

Then Lockdown Started and the result was delayed.

Finally, on 2nd November 2020, I received a mail from their side that I have been selected for the role of Systems Engineers at Infosys.

About Infytq

The Infosys Certification program is an examination to test your industry readiness by determining your knowledge in Programming and Databases. What you get by clearing the assessment is a certification that you can flaunt as well as a chance to get interviewed at Infosys on the same day!

If you are wondering what it takes, here’s what:

 

 

 

  • To register for the Infosys Certification, you must be a student of B.E., B. Tech, M.E., M. Tech, M.Sc., MCA or MCM, graduating in 2020.
  • You will need to score a minimum of 65% in the examination to get the Infosys Certification.
  • Students who score above 65% in the examination, will be eligible for an on-the-spot interview by Infosys!

My Experience

I have registered the infytq exam on the 25 June 2019(Tuesday) on the Infytq platform provided by Infosys. I have studied consistently all the section of infytq (Python Programming, Object-Oriented Programming, Data Structure, DBMS) with devotion and dedication. Infosys provides a great platform to learn and improve our skillsets. I have taken the infytq exam on 14 August 2019 (Wednesday), at Aeronautical College in Hyderabad.

Round 1: 

It was an online test with 2 hands-on coding problems and 20 MCQ’s (without negative marking) and the total time for the exam was 3 hr. The difficulty level of hands-on programming was intermediate. Mostly MCQ’s are asked on the DBMS and they are challenging enough.

E.g. They will show you 3-4 line query and table and we have find out how rows will be fetched after the execution of that query.

The hands-on section contains 60% weight to clear this section.

Hands-on Coding Question I:- Even-Odd Series

Given a string and it contains the digits as well as non-digits. We have to find the count of non-digits. If it is odd then remove all the non-digits and print the string as in even-odd order.

 

 

 

E.g. The given string is  */24#5%7&9*3@. We have to count the non-digit. It’s 7, odd. Then remove all the digits from the string and output will become (in a string) 254739. In the problem, we have only 2 even and 4 odd numbers then after the even number of completion print the remaining odd numbers.

Hands-on Coding Question I:- Pronic Number

Given a string in which random numbers are present and we have to find the product and the number(one is lesser and one is greater) who already present in the string. Confusing,  Let’s see the example:

E.g. Given a string contains 1203456. The multiplication of 3 and 4(one is lesser and one is greater) product become 12 and it’s present in the string. Like 4 and 5(one is lesser and one is greater) the product is 20 and it’s present in the string and so on. In such a way, We have to find all the numbers and in the output just we have to store the only product in the list like[ ’12’, ’20’].

If we haven’t found the product then print -1.

 

Round 2: HR interview

HR was a very cool person. Amoung 700 students only 10 are shortlisted for the HR interview. The following point he was asked:

How was your Exam?: It was quite difficult but I work hard to execute the programs. And told him about my preparation.

83.0% is it your first attempt?: Yes. It is my first attempt.

Tell me about your role in the internship?: I have mentioned the internship in my resume and he just goes through it.

Area of Interest: He just wants to know in which area we are interested to work.

Then the usual questions are started like where you came from? What’s your night plan? etc.

My interview lasted for 10 – 12 minutes.

 

Summary:

To crack the infytq you need to improve your coding as well as the DBMS concept very deeply and practically.

Round 1:

This was an online exam( i.e. allowed to take the test from any location) and was proctored by a webcam.

 

 

 

This round consisted of 40 mcqs and we were given 1 hour. 

  • 20 on Python/Java
  • 10 on aptitude
  • 10 on DBMS

I felt that Python section was quite easy. If you have atleast known the basics, you’ll get around 10 questions. In my case, I’m sure that I gave 15+ questions right. 

For me, aptitude questions were moderate and DBMS was not a big deal at all.

Have an eye on timer, You only have SIXTY minutes. If you stick on to aptitude, you’ll lose.

And to be remembered you will be given 1 mark for any correct answer, and 0.25 is deducted for every wrong answer.

The cutoff wasn’t disclosed.

A couple of weeks later, the results were announced and I was shortlisted.

Few weeks later, we were informed about the next round of certification and it’s date and venue. 

 

 

 

It was supposed to be on 21st march in our college. Due to COVID-19, the exam was postponed.

Later, we got a mail saying that the exam is rescheduled on 14th June and will be online as the first round.

Round 2:

Unlike the previous years, we were allowed to take the test online from home.

This round is a 3 hours exam and NO NEGATIVE marking.

The pattern of this round is:

  • Hands-on coding- 2
  • MCQs – 20

To be able to clear the exam, you have to score atleast 65% in the exam. 

The MCQs are mostly on DBMS, Python, Data Structures. Hardly 2-3 questions were appeared other than these topics. As I’m interested in DBMS, I gave 30% of the mcqs with ease. Overall, it was not that hard.

I passed all the test cases of both the programs. One was in the very easy rack and the other took almost 1.5 hours for me. 

As I cracked both the programs, I’m sure about clearing this round too.

On 6th July, I received a mail congratulating me for clearing the final round. This year the cleared students percentage is comparatively high. In my college, 4% students got to clear the final round. 

In the previous year, the student can reappear the exam after 3 months in two setbacks. But this year, there is no information officially regarding this.

The next round will be HR interview for the System Engineer role where the interview usually happens on the same day of the final round. But this year, COVID_19 changed the whole thing. The mail have mentioned that the interview will also be digital (e-meeting) and is yet to happen.

InfyTq is one of the most coveted events of Infosys, as this is the only way for many engineering college students from India to land a job in it. InFyTq used to consist of a single certification test, but due to increase in no. of candidates they have started a Screening round to shortlist candidates for next round.

I took the exam on 23rd, Sunday February 2020.
The exam format is of following:
The exam consists of 40 questions.
The programming part (Java/Python) consists of 20 questions.

The DBMS part consists of 20 questions.

The aptitude part consists of 20 questions.
The time to complete the exams is 60 mins. And keep in mind the exam is proctored by a webcam.
Many whose face could not be detected during exam were barred from giving it.

Now coming to questions part…

Programming MCQS

I found these questions quite tough and most of them included use of libraries and ds from core. I also encountered questions which were test study based. Even in case of Java questions related to JVM and core questions were asked. In case of Python the questions were quite complex.

 

 

 

DBMS

I found questions in this part quite easy as many questions were based on join(inner-join). Even many featured use of sub-queries and group-by utilizations. I even got a question from MongoDB which was quite easy(Just remember the order of changes).
To solve DBMS questions one needs to practice from InfyTQ platform.

Aptitude

Aptitude was the most easy part although one/two questions were time consuming (and tricky as well so I left them). Aptitude involved use of unary method of mathematics. Some involved probability and basic compound-interest. Don’t take it lightly as you will get some questions from mensuration and advanced trigonometry.

Conclusion:

Just basic knowledge of the subject and well retention of basic maths formulae will help you skid pass 20 questions as ease.

I am eagerly waiting for my results. Good luck to you!!!

Hello Everyone, I am here to share my experience with my InfyTQ journey. InfyTQ is a certification exam which also offers placement opportunity.

I was a zero to programming, and I was wondering how I am going to clear this round. I have only practiced 15 days on hackerearth algorithm section especially string manipulation. Then I got to know I have to clear the screening test before the actual round because in 2019 there was no screening test but there were taking it in 2020. So I have learned MCQs through many MCQ sites.

Round 1: My 1st Round was Conducted in the last week of Feb 2020. I was very excited about this round. And This exam is divided into 2 sections and each section having 20 questions. Section 1 had an Aptitude Question which is of the Basic level. Section 2 had an Objective type Question which is of Medium and this question is from Programming Language (we have a choice between Python & Java, Which we have to choose during slot Booking), Data Structure, DBMS [MySQL and 1 question is from MongoDB]. I chose python.

I Got my result after 4-6 days and I Qualified for Round 2 Successfully

Round 2: My round 2 Exams were scheduled for the last week of March. But, Due to COVID-19, it is scheduled a few more times. And finally, it is conducted on the 3rd week of June. This exam also had 2 sections. Section1 had 2 Coding Questions, 1 question was easy and another was medium. Section 2 is the same as round 1. And to clear this round one has to score more than 65%.

 

 

 

Note: If you are zero to programming/python/database 15 days of hard work is enough to crack all the rounds.

We are the four friends who were preparing for it from the beginning, and we all are clearing these rounds easily.

Interview: My Interview was scheduled for 24th Nov. And I got the mail just 1 day before the interview. My Interview was 35-40 min. long. 

I don’t know why my interview goes that long because my friends were having only a 15-25 minute long interview 

The question that the interviewer asked:

  1. Tell me something about yourself.
  2. Tell me something about your projects/certifications.
  3. He asked me to share my screen to make a prime number program and simple file handling program in python.
  4. I have mentioned the latest tech like ReactJS, MongoDB so he asked questions from these techs (Basic).
  5. Technology awareness questions. (if I am aware of cloud, machine learning, etc.).
  6. Some data structure questions (array, linked list, and their difference, etc.)

Note: Keep a smile on your face during the Interview it gave u confidence and positivity.

I got my interview result after exactly two weeks. I was selected and happy (Role: system engineer) just after 2 days, there is mine up-gradation test #no-preparation

Upgradation Test: There was 3 question contain 50 marks (easy), 75 marks (med), and 100 marks (hard). 

 

 

 

  •  Question 1: Write a program to add all the natural numbers till N but in binary.

    • Python3

     

     

     

    #input: 2(value of N)

    #output: 11

    #Explanation:  binary of 1= 01

    #binary of 2= 10

    #01+10=11

      

    result=0

    for i in range(1,N+1):

           result+=int(bin(i)[2:])

    return result

  • Question 2: Longest Common Subsequence in two given strings. I have used python as it was my favorite till this test. I don’t know why it is getting the time limit to exceed and only one test case gets passed. After discussing it with my seniors. They advised me not to use python in CP.

I was disappointed with the result but guess what they are taking this round again due to technical issues. I got a second chance Tomorrow is my re-test. I don’t want to disappoint myself this time as I was learning Dynamic Programming since last week and I have also switched to C++ as one can give this round in any language. Let’s see what happens. 

Dynamic Programming learning: Initially I have watched a youtube, he is best at teaching dynamic programming. And I was reading articles and practicing on the Geekforgeeks platform. Geekforgeeks has all standard as well as ques variations on its platform. Learn the DP section from Youtube

InfyTQ certification exam was started by Infosys in the year 2019. Its completely based on python programming.
To clear the exam 65% or more marks is required
The benefits of clearing this test includes:

  • You will get a professional certification on python from infosys which will be valid for lifetime
  • On spot job interview and an opportunity to join infosys

I will be sharing my experience and few questions that will help you understand the pattern.
The test will have 2 sections.

  • 2 coding questions
  • 20 MCQ from DS, Algo, DBMS, Programming

Time provided will be 2 hours. Coding questions will be from string manipulation, list or array, matrix or 2d arrays.
Few question that where asked from 2020 batch:

  1. Given a list of string and numbers, rotate the string by one position to the right if the sum of squares of digits of the corresponding number is even and rotate it twice to the left if the sum of the squares of the digits of the corresponding number is odd.
  2. Given an array, find the sub array which can be a square matrix with maximum sum. If there are multiple results print the matrices in the order of their orders( i.e, 3×3 matrix will be printed first, then 2X2…so on)
  3. Given an alphanumeric string, extract all numbers, remove the duplicate digits, and from that set of digits construct the largest even number possible
  4. Given a mxn matrix select an element if the same element appears at 4 consecutive position again. Return the minimum element from all the gathered elements. What is consecutive? It’s horizontal, vertical and all possible diagonals
  5. State whether a giving string contains matching braces or not. In case mismatch is present then output the index of mismatch position
  6. Longest Alphabetic Sequence
  7. From a alphanumeric string extract all digits, From the smallest odd number with no repeats.

Round 1: My 1st Round was Conducted in the last week of Feb 2020. And This exam is divided into 2 sections and each section having 20 questions. Section1 had Aptitude Question which is of Basic to Medium level. And section2 had Objective type Question which is of Medium to High level and this question is from Programming Language (we have a choice between Python & Java Only: Which we have to choose during slot Booking), Data Structure, DBMS(MySQL and 1 question is from MongoDB).

I Got my result after 3-4 days. And I Qualified for Round2.

Note: Study material available on InfyTQ is best for clearing section2 of Round1 and it also helps you in Round2 (As the difficulty level and question type are almost the same.) But, the material is only available in Python programming language.

Round 2: After getting my round1 result, My round 2 Exams were scheduled for the first week of March. But, Due to COVID-19, it is scheduled a few more times. And finally, it is conducted on the 3rd week of June. This exam also had 2 sections. Section1 had 2 Coding Questions, 1 question was easy and another was medium. Section 2 is the same as round 1.

 

 

 

I got my result, in the first week of July and I also qualify for this exam.

Interview: My Interview was scheduled for 2nd October. And I got the mail just 2 days before the interview. My Interview was 17-18 min. long. The question that the interviewer asked:

Interview Begins with my Introduction.

  1. Which programming language do you choose for the exam? (Ans. Python)
  2. Why you choose/ learn python? Why not another language?
  3. What is Exception Handling?
  4. What is Tuple?
  5. What is DBMS?
  6. What is RDBMS?
  7. What is Data structure?
  8. What is a Linked list?
  9. Type of linked list?
  10. What is OOPs concept?
  11. What is Encapsulation?
  12. Ask About My projects?

The last question was on my Hobbies- which game you are playing now as PUBG is banned?

I got my interview result on the 7th of December through the mail, where it is mentioned that I am selected for the role of System Engineer at Infosys. And I also have an exclusive opportunity to appear for the selection for a higher role such as System Engineer specialist and power programmer. And If I do not qualify for the higher role through the upgrade test, then you will retain the role of System Engineer at Infosys. 

Upgrade Test: My upgrade exam was scheduled for 13 of December and I got my mail just before 3 days. The upgrade test was conducted on Hacker Earth and it was not a web-protected exam. This exam has 3 coding Questions – Easy( 50 points), Medium (75 points), Hard (100 points), total 225 points, and the points are assigned according to the number of test cases you pass.

(EASY- 50 points) Question 1: Write a program to add all the natural number till N, but not In decimal, do it in binary.

Example1:


 

input: 2(value of N)
output: 11
Explanation:  binary of 1= 01
binary of 2= 10
01+10=11

Example2:

input: 3
output: 22
Explanation:  binary of 1= 01
binary of 2= 10
binary of 3= 11
01+10+11=22

Example3:

input: 4
output: 122

MyCode (In Python): (Inside Function)

total=0
for i in range(1,N+1):
       total+=int(bin(i)[2:])
return total

Note: Even though My code was right and it was working fine in all sample input that I was entering manually. But this code was only passing 1 test case and the rest of the test cases are unable to pass due to the Time limit. (Sadly, I Only get 3 points out of 50.)

(MEDIUM-75 points) Ques2: Calculate the sum of Ai/Aj, where A is an Array of N numbers?

Example1:

Input: 3 (N no. of elements)
1 3 2
Output: 9
Explain:
1/1 + 1/2 +1/3 =1+0+0=1
3/1 + 3/2 +3/3= 3+1+1=5
2/1 + 2/2 + 2/3= 2+1+0=3
1+3+5=9

My code was unable to pass 2 test cases due to the time limit, but the rest of the test cases successfully passes and from this question, I got 55 points.

I was unable to solve the 3rd question. Let see what happens(waiting for result)

Round 1:

Online based exam conducted at an exam centre where the exam has two sections: 2 Coding questions to be solved in Python3 and 20 MCQs based on DBMS (SQL), OOPs (Python) and Data Structures and Algorithms. MCQs were  moderately easy as it was asked similar to practice questions, quizzes in InfyTQ platform.  Among 2 coding questions One will be easy and other will be moderately tough.There is no need to prepare advance programming concepts like DP, Backtracking etc atleast for this round.They will be asked in the further rounds if you clear this certification exam.

My Questions:

 

 

 

  1. A simple String rotation type question where INPUT will be given in the form of Dictionary  and based on the value of the Dictionary the STRING should be rotated either clockwise or anti-clockwise.
  2. It is based on matrix which i felt  a bit difficult. We  have to find the number which occur consecutively 4 times either in a ROW, COLUMN, DIAGONAL and more importantly REVERSE DIAGONAL. If there are multiple such elements find the minimum among them.If there is no such element print “-1”.

Round 2:

Among 200 + students only 8 students were able to clear the fist round and among that 4 were from our College.

and coming to the next round it will be behavioral assessment round (HR round) where they will ask about our interests, family details and about INFOSYS. It continued for 10-15 minutes for each person and they said results will be sent soon to our respective colleges

 VERDICT:

ALL 4 MEMBERS FROM OUR COLLEGE ARE SELECTED  AND WERE OFFERED ENTRY LEVEL JOB(SYSTEM ENGINEER) AT INFOSYS

Considering the feedback from all my friends i can say that clearing the exam is very easy if you are good at basics of python and fairly better at problem solving skills.

GOOD LUCK:)

Through Infytq Exam we have two opportunities-

  • Becoming an Infosys Certified Software Programmer Infosys Certification
  • Getting selected as System Engineer at Infosys

Round 1 (Online Test ): It was a web proctored round. There were 40 MCQs and the time was 1 hr. 20 MCQs were on the programming language that I have chosen while registering for INFYTQ.

  • I Have chosen Java but there were two options Java and Python.

10 MCQs on Aptitude and 10 MCQs on D.B.M.S.

Aptitude Questions were of the easy level while D.B.M.S questions were mainly on SQL queries and the level was medium.

The cutoff of this round was not disclosed by Infosys, they were directly sending mails to the participants who have cleared this round.

 

 

 

Round 2 (Offline Test): Now, all the participants who have cleared the Qualifier Round were invited for the final round at an Infosys verified Exam Center (In my case it was Galgotias University). We were required to arrive at the exam center within a particular time slot with our Infytq Admit Cards.

In this round, there were 2 Programming Questions (1 easy, 1 medium) and 20 MCQ questions on D.B.M.S and Java/Python.

Note: You are required to code in the same language that you have chosen.

After 30 minutes I got the mail that I have cleared this round and now you are required to give the H.R interview.

So, After clearing this round I become eligible for Infosys Certification.

Round 3 (HR Round): This round held at the same place. This round was easy. It was just a behavioral round.

The H.R was a lady, and she was a very soft-spoken person. So, I didn’t feel any nervousness.

Some questions that she asked-

  1. Introduce yourself.
  2. How’s your college life going?
  3. Why are you doing Computer Science Engineering?
  4. Why do you want to join Infosys?
