The interview process had 5 rounds:

• Recruiter screen
• Coding 1 (DSA)
• Coding 2 (Code Design)
• Leadership
• Values

Firstly, the process was very well organized and transparent. The recruiter shared a lot of information related to expectations before each round, and feedback after each round was provided within a reasonable time window.

Coding rounds: In my opinion, there was very little difference between both of them. The Code Design was very similar to the DSA round, with just a slightly more complex problem.

Leadership and Values are both quite peculiar rounds for me. Mostly overlapping questions.

Feedback: Generally, I passed all rounds with good feedback. However, some comments were somewhat surprising:

1. The Code Design round: The scale-up solution was not as elegant as the initial one. I'm not sure what an elegant solution could be achieved within a 45-minute time slot.
2. Leadership and Values: Some answers did not explain the problem in detail, for example, the conflict that took place, or similar.

In the end, it took more than 2 weeks after all rounds to get to the offer. I was downgraded to a Senior role mainly because of the values/leadership feedback. My leadership skills are generally impressive but not as good for a Principal role. I rejected the offer and accepted a comparable Principal role at a different company.

Coding (DSA) - Top K items problem

Coding (Code Design) - Rate limiter

System Design - Tagging system

Values/Leadership - Typical behavioral questions
