Exactly 60 mins Interview

2 Theory questions [To be solved in 10 mins - 5 mins each]

1. Facebook question - find number of friends given tables 'Users' and 'User_relationship' with indexes mentioned
   Just asked to give approach, I gave SQL query as well.

2. Given Architecure of Google Docs with some pointers (dont exactly remember):

• Multiple user can access and edit single doc.
• Every doc will be served by a dedicated single server.
• One server can serve many documents.
• Load Balancer following Round Robin Strategy.

Open Ended Question, didn't ask anything in specific :

• Q. What are your thoughts on this architecture?
• Q. What are some scenarios that can happen and what might be a good solution for that?

3. Coding Questions - https://leetcode.com/problems/text-justification/ (not exactly this but modification of this question)

Was able to solve this questions with all cases passing with just 2 mins remaining (max 45 min for this qs), then talked a little about time complexity and just chatted with the interviewer.

Result - Got Rejection email after 2 days :)
