Technical Behavioral
I first talked to a recruiter. Then, there were 2 rounds of interviews, both onsite. The first round was about 90 minutes with one developer, which I thought was great. The second round was 4 hours long and involved meeting with 4 different developers. All four had a technical part, and two of them also had a 'fit' part. They asked pretty standard interview questions like breadth first traversal, stream processing in C#, tic tac toe game, and an open-ended design question. I didn't nail all the technical questions because I was running short on time in every stage, but I think I showed I was competent in most areas. They really want to see how deep you can go, even into OS or compiler level stuff.

Technical Coding Behavioral System Design Other
It started with a quick call with the recruiter, then a technical interview lasting an hour. This interview involved some pair programming and discussions about my past experiences. The onsite part was a set of hour-long sessions: a whiteboarding session that featured a standard algorithm problem where I could reuse code, a cultural chat which was friendly but intense, focusing on how I handle workplace adversity, a system design session with a typical open-ended problem, and a final Q&A session to learn more about the company.

Coding Behavioral Technical System Design
It was a three-part interview process. First, a quick chat with the recruiting team. Then, a one-hour technical interview with two coding questions, followed by behavioral questions and a chance to ask about the company. Finally, a four-hour onsite interview with four interviewers. Each had a technical component involving whiteboarding, with difficulty varying from easy to pretty tough. I managed to answer all technical questions within the time and also discussed the company with some interviewers, some were direct, others more friendly. After the last interview, I was told they'd have a meeting the next day and I'd hear back by the end of that day. It seemed like a pleasant experience until then. Several weeks passed with no response, even after I tried emailing and calling. It's unprofessional to not hear back or be ignored, especially when you expect feedback quickly.
