A recruiter reached out on LinkedIn.

I cleared the phone round.

The onsite consisted of two coding rounds, two system design rounds, and a behavioral round.

Most of the questions were medium/easy LeetCode problems.

Except for one interviewer, all the others had less than two years of experience.

I received a rejection email from the recruiter four days after the onsite, with no feedback.

They lacked the courtesy to call and inform me. This was quite unprofessional on the recruiter's part.

1. Intersection of two lists.
2. Find the bad version.
3. System design: Twitter trending topics.
4. System design: Live update of comments for posts.
