The tech interview process consists of three rounds.

The third round is conducted by the team leader.

Each round begins with a briefing of your projects (as listed on your resume).

This is followed by a 20-minute system design session, typically covering one to two systems.

The interview concludes with a coding exercise and time for questions.

These interviews will be conducted within two weeks.

The first two interviews are friendly.

However, the interviewer for the last round was late, rude, and arrogant.

• Describe your previous projects, going into detail.
• Design a Twitter-like pub-sub system.
• Design video stream live comments.
• Design a rate limiter.
