Google Interview | L4 | Interview
Summary
I had a phone screen interview with Google for an L4 role, where I was asked to design a custom Deque using only a HashMap. Despite performing well and impressing the interviewer, I was unexpectedly rejected without specific feedback.
Full Experience
Recently I had an phone screen round interview with Google. I was preparing very hard for this interview fast past few weeks.
I joined the interview, Interviewer greeted and made sure that i was comfortable enough before proceeding. He told me he will only ask 1 question so i don't need to worry alot. Then he gave me the problem to design a custom Deque (including all deque methods) only using a hashMap. In the begining i got confused but just after a minute i realised its fairly easy question. I explained the approach of using index as key and interviewer was satisfied. He asked me to code the approach. I coded it, covering all edge cases as well. The interview ended on a great note.
I was really excited about the result expecting a Strong Hire/ atleast Hire. Next day i got the call from the recruiter. She mentioned that they can't proceed further with me. On asking for feedback she mentioned they don't have any specific feedback. I really did great even interviewer was impressed but still it turned out to be failure. Not sure, they were just palying with the candidate's emotions or really wanted to hire.
Anyways I have a 6 months cooldown period now. But TBH I don't feel like interviewing for Google ever again. Really disaapointing.
Please comment if you had a similar situation.
