Interview Preparation Tips
Interview preparation tips for other job seekers - I got a call from recruiter and we scheduled one-on-one interview. For the hoisting question, I explained that hoisting is behavior where all declarations are moved on top. But the interviewer was outright rude and told that is an answer given by someone who doesn't know JS and not experienced person. Not accepting an answer and asking to explain in detail is one thing but calling out on candidates and mocking is outright rude. I got similar rude replies for other questions.
In ds round, for removing duplicates from array, I was using standard two pointer solution where complexity was 'N' but I was asked why such complicated solution for simple question. I was advised to use hashmap or two loops. First time in my experience where an interviewer has told me to increase the complexity because the optimized solution looks complex.
For the second question - reverse a linked list, it was not even 10 minutes and I was about to finish my coding with right answer(He did not even bother to ask how I solutionized). He told I'm taking too much time and he asked any other question and abruptly ended the call. My interview was scheduled for one hour in which he asked couple of js concept questions, js coding and two dsa questions and it was over in 35 minutes.
