DSA , OOPS , and JAVA Questions:

Brief Introduction of myself .
-
Given a map of < Name (String) , Age (Int) > , you have to delete all the names whose age is greater than 20 , without using extra map , you have to delete inplace.
I tried this in both cpp and java , but in both I failed actually whenever we delete some value of map while iterating it will behave improperly.Learned something new after this round.
-
OOPS Concepts like polymorphism , inheritance , real life examples.
-
JAVA questions like Interface vs abstract class , collections etc.

Print all the Special numbers in the range of [1 , 10^9].
Special Number : A number is special if the difference of adjacent digit is 1.
For Ex : 12 , 23 , 34 , 121 , 1232 . . . . .
Solution -> 1) Brute Force 2) Use BFS

5. Hiring Manager [Face2Face (Virtual) ] [1 hour]:
DSA , Project ,and LP (Leadership Principles) Questions:
- Brief Introduction of myself .
- Asked about my project , and sadly it seems either I am not able to explain him properly or he didn't found my project/work that much intresting.
He : Tell me from last some months what extra you did , frankly speak becuase on work level I don't think you have enough experience .
Now I was like , God please please I am in 5th round and this is HM , please ye nikalwa do .
Me : DSA.
He : Ok , so now tell me which DS you know .
Me : Arrays , Stack , queues , heaps .
He : Or ?
Me : Graph , DSU(Disjoint Set-Union) , and Tries.
He : Oh great , what is this DSU please explain
Me : I explained , with proper diagram.
He : Ok but what is the practical use , or where we can use this DS and technique.
Me : Yes we can use in MST (Minimum Spanning Tree) , I gave an example , but wait actually he asked why the cost from A to B is not minimum , I am confused too actually he mixed up the MST with Dijkistra and whole discussion is going in this direction only , my motivation already goes down and after this question they asked me some general questions on LP.
Final Result : PayPal recruiter really ghosted me , I tried to contact with them for a month continously via mail and call , but there is no response .
After a month I got call from another recruiter for hiring but sadly they hire for 2021 batch , but I shared my above incident and requested please check some how result and she checked and confirmed I was Rejected in Hiring Manager (as expected) Round.
