Round 1-Coding round: platform – hackerrank
- Everyone got different questions
- Questions 1 and 2 were easy and mostly implementation based.
- Question 3 was medium and based on the Range update query. Refer this
- Question 4 was a 2D Dynamic programming question
(I solved 1,2 and 4 completely and 3rd partially)
Round 2- Technical Interview-1:
- The interviewer was our college alumni, so he asked some informal questions about college life and professors
- Then he asked me what is polymorphism
- Then he gave me code based on polymorphism and asked what will be output
- Coding question – Keep removing palindromic substrings from a string, till there is no palindromic substring. This is a pretty famous interview question. I explained the stack-based approach, and he asked me to write pseudo code and asked for a dry run of code.
(I was not able to explain polymorphism but he was impressed with my code for the problem and went to the next round)
Round 3-Technical Interview-2:
- The interviewer asked about sorting algorithms, then asked me to write bubble sort. The interviewer was not convinced by the code that I wrote.
- Asked applications of stack and queue (give real-life application. here’s the link)
- Asked how you have used node in your projects
I got rejected in this round.
There was an HR round too. 20 students from our college were selected.
