BNY Mellon Interview Experience (On-Campus) 2023

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.
