Initially, a recruiter from PhonePe directly mailed and scheduled a machine coding round. There were multiple interviewees. The interviewer shared her screen with the question. We were asked to share our screens while coding. 1.5 hours were given to complete coding and send it to them.

A code evaluation round took place on the same day for 15 minutes.

Then, another three rounds were scheduled with different people:

• A problem-solving/data structure round
• A system design round
• A hiring manager discussion round

I was expecting very difficult problems for the problem-solving round, seeing some suggestions on GeeksforGeeks, but I could have easily cleared it by just revising basic data structures. I think this part depends a lot on the interviewer.

Design a multi-layer cache system with certain rules on reading and writing.

For a given array, with each item representing the number of floors in buildings from left to right, if the sun is on the right, how many floors will get sunlight?
