- Onsite Rounds (f2f)
Machine Coding Round :
This was the most exciting round. Problem was to do 3 operations on very large numbers.
- Problem Solving Round –
In this round, he started with the discussion of Machine round problem. Then he asked me for a simple problem. Find the first occurrence of a digit(1-9) other than zero in a stream of integers in less than o(n). Given I can’t have the access to the memory location where the stream is written.
He basically wanted to know how I think and how many approaches I can think of, and whether I can challenge him or not that it is not possible. and yes I did.

Why do you want to join Flipkart? Then What would you do if something goes wrong on production, and you are unable to find the bug, etc?
Them he discussed the projects I had done in my previous company.
