Summary
I interviewed for an SDE4 role at WEX in Bengaluru; I was asked to write code to compute folder sizes and design the payment component of a ticketing system, and was ultimately rejected.
How it went
1st Round:
Write code to compute the size of all folders in a directory. No instruction if the interviewer wants it to be LLD or more from problem solving lens. I had difficulty understanding him due to his thick accent.
2nd Round:
LLD for payment part of bookmyshow. He wanted me to cover booking part as well initially but I told him it'd be too much to handle.
No detailed feedback received so not possible to understand his perspective.
