Interview
Applied online, but also attended a university event. No online assessment.
The first round is a 30-minute talk with the hiring manager, basically going through the resume and some behavioral questions.
The second round is a 1-hour technical round, and it's a backend pair-programming task. Wrote a simple task scheduler and discussed how I can scale this up(distributed system concepts)
The two rounds are 2 weeks apart.

The first interview was an introduction call with a recruiter where you just explain your cv and chat about the company. Then if you proceed is a technical interview where I was asked a medium leetcode-like question. If you pass it the 3rd interview is meeting with supposedly your manager.
