Coding System Design Technical
It was a 1.5 hour technical interview with HR. I didn't get any feedback, just told they are moving on with other candidates. I think I did well on the first question and system design, but the second question was tougher. I mentioned solving it with all combinations, noting it's an NP-complete problem.

HR phone call where we discussed my background and what they're looking for. Then, a 2-hour first technical interview over Zoom. It involved 3 questions: 2 coding questions similar to LeetCode's 2 Sum and a system design question. The interviewer was very nice.

So, the first interview was with the team leader, which was a technical interview. If that went well, the next step was an interview with the group leader. After that, there was a third interview, and then potentially a call to HR. Overall, the first interview was a good experience, even though I didn't get the job.
