1 round of test and 3 rounds of interview.

Test:

• 8-10 McQueen's questions on CS concepts (OS, Networking, etc.)
• 2 coding questions: 1 was fairly easy, the 2nd was slightly tough (on DP, don't remember the questions exactly).

Interview:

• 1st round: Taken by an SDE. Questions on CV, then some questions on OS, networking concepts. 1 coding question which is medium level (something on hash map).
• 2nd round: Taken by a senior engineer/VP. A very open-ended question to design a system architecture for COVID (this was the exact question, no other input was given).
• 3rd round: HR. Generic HR questions, on what is your interest apart from software, how do you resolve differences with a colleague, etc.

Design the system architecture for a COVID-19 system for the public.
