Interview started with introduction, took approximately 5 mins.
Next, there were five scenario based questions for system design which were allocated 20 minutes. I remember only 3 of them.

1. There is a mobile game for which we have a library which analyze the completed games and provide suggestions to the user. We can either store that library in our client's phone or on a server which can compute and analyze. Discuss advantages and disadvantages of both.

2. We are working on a photo storage application. Your task is to come up with estimates for storage for the next year. Which information would you consider for coming up with estimate.

3. We have machines across geographic locations around the world. Every midnight each machine will emit analytics if there are any issues with it. At 1 AM we patch the servers based on these analytics. What problems do you see in this design?

I do not remember the other two questions.

After these I was asked to solve coding questions in 30 mins.

1. https://leetcode.com/problems/subdomain-visit-count/solution/
2. Second question was to find longest contiguous subsequence, similar to https://leetcode.com/discuss/interview-question/460449/Longest-Contiguous-Sequence

I was unable to complete the second question however was very close to completion, interviewer got the idea about the solution of the problem. I am yet to hear result for this interview.

Thanks for reading, happy coding.

Cheers
