Behavioral Technical Coding
So, I had 6 interviews in total. It started with a 30 min HM screen, then a 60 min technical screen. After that, it was 4 back-to-back 60 min interviews. These were a mix of talking about background/teams and then technical/solution-based questions. They asked a pretty wide variety of questions, and surprisingly more SQL than I expected, which was tough since I've been purely NoSQL for the past year.

Technical Behavioral Presentation
It started with a take-home test, then went into 4 rounds of interviews plus lunch. Their process is similar to other big tech companies, but they include a manager interview along with several technical rounds. Don't be too concerned about the complexity of the multiple interview rounds; it's more about whether you possess the specific skills listed in the job requirements and the technologies they currently use. The manager round was quite unclear. If your skills aren't an exact match for what they need, it's probably not worth your time. After dedicating days to HR and a full workday to interviews, I received a rejection email without even a phone call to explain the outcome.

Technical Coding
It began with a recruiter chat, which was brief and efficient. Then came a technical interview that was also very professional. The interviewer was helpful and gave me some pointers on the questions. They also offered advice for upcoming interviews and how to approach them.
