There were two phone calls before any technical discussions. The first was with the recruiter, and the second was with hiring management. These calls are meant to learn about each other outside of technical skills. It's good that they are doing this instead of just jumping right into brain teasers, like some other companies do.

Then, there was one technical phone screen. It covered a fair amount of knowledge relevant to the job, as well as a coding exercise via Collabedit. The interviewer was kind enough to send me feedback directly afterward upon request; candid feedback is real here.

Next, the first onsite round included two technical interviewers and two management interviewers. I was stopped here because my technical skills did not meet the need. The technical questions asked were fair, given they are very frank about looking for experienced candidates. It's natural that some questions you just can't answer because you haven't dealt with those problems before or haven't used a certain aspect of a language. The interview was pretty heavy on multithreading and covered a wide spectrum of Java programming skills.

In the end, the recruiter called me to deliver the disappointing news in person rather than just via email, which was also nice.

Overall, it was a very positive experience for me. I have less doubt about the company culture after the interview; they truly care a great deal about it, which is reflected in their interview process. Their culture is obviously not for everyone.

Multithreading, concurrency, distributed computing.

Many culture/personality related chats, but I don't find the answer. Just show yourself.
