The interview process involved:

• One phone screen with a recruiter.
• Multiple phone screens with engineers, two of which included coding challenges.
• One in-person interview with multiple people in-office.

The entire experience was very professional and often enjoyable. The engineers and recruiters were personable and extremely helpful. Their method of doing code reviews via a shared IDE was refreshing, as it allowed the process to feel more like a pair programming challenge rather than a test.

Standard programming interview-type problems.

To their credit, they were all unique and had been chosen by the person giving the interview. This meant they were interesting problems that the interviewer found to be good measures of ability.

I was impressed by how rigorous the testing was. They certainly don't skip steps in determining the quality of their potential engineers.
