    Average Interview


    The interview process was very smooth. Recruiting was very responsive and seemed genuinely interested in figuring out what team would be the best fit and moving me through the process.

    I had a phone call with a recruiter to determine team fit and a day of onsite interviews, but this may have been an abbreviated process since I was under time pressure from other companies. The onsite consisted of an architectural question (design an API, describe the backend with some constraints), a pair programming style interview, and behavioral interviews.

    Everyone I interviewed with was very friendly and seemed like folks I would enjoy working with. All in all, I really enjoyed the interviews compared to some more aggressive interview experiences I had with other companies.
