System Design Behavioral Coding
It was a thorough and pretty open process, the interviewers were good and competent, they really represented the company and the kind of people who work here. I had 2 system design interviews where we talked about redesigning and monitoring distributed systems for GDPR PII compliance, especially the right to forget, and one interview that was a standard culture fit, focusing on action, response, and outcome. There was also a coding interview, and a fifth one that I can't recall.

Technical Coding System Design Behavioral
It was a pretty standard process: first, an HR call (30 minutes). Then, a technical interview with a very easy coding problem (60 minutes). After that, a System Design interview (60 minutes). Following that, a Behavioral interview (60 minutes). Lastly, a 'Bar raiser' interview (60 minutes - think Amazon's Bar raiser concept). The initial interview was quite straightforward, with common technical questions and approaches. The coding problem was extremely light, and we had plenty of extra time for more discussion. I'm not great at system design, and I think I spent too much time on the initial problem definition, leaving little time to go into design specifics. This led to my rejection after waiting over a week, even though I tried to follow best practices like understanding the problem, considering constraints, asking questions, listening to feedback, defining APIs, and drawing diagrams. The biggest issue was the complete lack of feedback, which really soured the experience for me.

Technical Coding Behavioral System Design
Applied online, got a call after 15 days for HR screening. The interview process involved three 1-hour rounds. The first was a Technical Round: 30 mins for a LeetCode medium problem and 30 mins for technical questions about my experience and CV. Next was the Hiring Manager Round, which focused on projects, past experience, my contributions, and culture fit. Finally, the Bar Raiser Round, with an Engineering Manager from another team. It had 30 mins for problem-solving and 30 mins for real-time scenario-based technical questions.
