Razorpay Product Development Engineer interview questions

I received a call after around 3 weeks of my application but rest of the process was quick. First round - Machine Coding round. I was asked to create an LLD. Second round - HM round. I had a direct one on one interview with the hiring manager.

2-4 rounds 2 technical and 1 HR rounds, 1st round have average questions but next round the difficulty level gets one level up and if requires they will set up one more technical or else Last round will be HR.
