I saw a post by recruiter on LinkedIn and contacted him via InMail. The recruiter contacted within few days asking basic details. Then radio silence for 3 weeks and then got a call from scheduling team for scheduling interviews

Screening Round
Taken by a Principle MTS. I was asked 1 DSA question:
Q: A conference will be for d days. A schedule of n interviews is given with 3 arrays for start, end and knowledge gained. The interview start time and end time are in days and each day the maximum number of meetings allowed to is k. I need to maximize knowledge gained.
-> Solved fully

Got a call from recruiter within 2 days for scheduling LOOP rounds:

Technical Round 1:

I was told to draw the HLD for a social media posting app like instagram. I completed following:

• Functional Requirements
• Non Functional Requirements
• DB Schema
• DB resilient design
• Services
• Diagram
  We discussed DB choices and reasoning, design decisions, CAP theorem etc.

Tecnical Round 2 (Taken by Director of Engineering):

I was asked basic JAVA Programming questions at first which I answered.
Then I was told to solve a hackerrank question. It wasn't realated to DSA but it was a very long and complicated question. I solved it but only 2 test cases passed out of 10

Tecnical Round 3 (Taken by a Principle MTS):

• Java Classes and coding related question
• Level Order traversal for a non binary tree.

Bartender Round:

Taken by someone from different team. I was asked multiple behavioural and questions related to my project. The interviewer was very rude and it seemed like he wasn't even interested in hiring.
