Question

Interview Expereinces of Hackwithinfyi 2022 : - https://www.desiqna.in/4605/interview-experiences-infosys-hackwithinfy-2022

Answer 1

In this post , shared some of the best resources and strategy for incoming SE, SES, and PP interview and even for TCS Interview too.

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 1.1k[ JAVA , (If u r sure then only write ) ]
  4. LINK4 1.2k[Python]

`

`

• Resources for DBMS / MySQL

  This subject is very important they ask anything either very easy or in very deep so prepare well and especially SES and PP guys u have to be more careful.

  1. LINK1 1.9k
  2. LINK2 654
  3. LINK3 400
  4. LINK4 401
  5. LINK5 1.2k (Query questions , Very important)

  If u have time then u can watch main topics of DBMS Sanchit_Jain_sir 882

`

`

• 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 925
  3. LINK 430
  4. LINK 344

`

`

• Resources for CN

  Mostly they ask few questions for PP role .

  1. Ipv4 VS Ipv6 , TCP/IP , UDP (Most common)
  2. LINK 574
  3. LINK 293
  4. LINK 176

`

`

• 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 174
  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 695

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
  15. Inorder successor of given node in BST
  16. Next smallest Palindrome
  17. Array sum using recursion
  18. Matrix rotation 90 degree.

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

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.
