Interviewed for SDE2 position on the Prime Video team.

Round 1 - System Design. Design Twitter, focus mainly on user timeline and posting a tweet features. Later, the interviewer also asked about how I would design the ads service in order to monetize the application.

Round 2 - This was a bit vague. I was given a use case and asked to write production grade APIs. The use case was to receive data from multiple sources (user feedback on amazon, user emails, etc.), process the text data and eventually power few insights and dashboards on the backend.

Round 3 - Coding question. Given a string with only alphabets and numbers, find the longest substring with equal number of alphabets and letters. E.g. Input - "abcde123". Answer would be "cde123".

Round 4 - Coding question. Word break problem from leetcode. https://leetcode.com/problems/word-break/

Note: Every round had 20-25 minutes of Leapdership Principles questions. I highly recommend having at least 2-3 stories ready for each of them.

Good luck.
