Online assessment:
Got 2 questions
- https://leetcode.com/problems/longest-happy-string/
- Given a code and ask debugging (Given a strictly increasing sequence of number n numbers from 1..n+1, fix the code to return correct output.)
Onsite: (Virtual - 4 rounds - 45 min each with 15 min break between the rounds)
ALL the interviewers very polite and professional.
Round One:
Behaviour: Time you identified/uncovered a critical issue and saved the disaster that might potentially happen in your team.
Coding: Implement write through cache(have to write both in cache and DB before returning success) in a multi threaded environment. Read heavy system.
Round two:
Behavior: How did u resolve conflict with your collegue
Coding: Implementation C++ file processor. Eg: Given a array of strings as follows. return the valid array of strings.
#define FOO
#undef BAR
b
#if FOO
c
d
#endIF
#IF BAR
e
f
#endIF
the result set should contain b,c,d not e f
Round three:
Behaviour - skills you would like to improve.
Coding: code IOC functionality without library
IOC.register(classidentifier,....)
IOC.get(classidentifier) - return the registered object
Round Four:
Behaviour - Situation when u took the customer/client feedback and acted upon/delivered it.
Coding:lock and unlock library without using any inbuilt library in multithreaded environment..
Did not expect complier level design questions since i have worked mostly on end user applications. Hence got Rejected.
Hope this post will be useful for some out there who is preparing for job interview like me. :)
