HR was very responsive to any questions, and I would almost always get responses in 24-48 hours of sending an email. The overall process was pretty good, first went through a phone interview, was told that I had passed it within a day or two, then went to an all-day onsite, where I had four technical interviews, a lunch interview, and a founder interview. Overall a great experience, probably the best that I had so far.

I had behavioral interviews and then 4 in person interviews. The behavioral was straightforward. There was also a data query interview where they taught you a new "language" and had you execute basic queries in it. Then there was a system design interview. I had two of these. The last one they asked me if I was deployed to the moon to identify new species of alien what kind of system would I build.
