I connected through a recruiter and was told that they moved very quickly, holding only one technical interview and that they gave candidates feedback the following day. The first interview was very technical in nature. I was shown technical diagrams and asked to describe them, then asked high-level questions about several languages. They stated again that they moved quickly and that I would have feedback the next day. Two days later I was asked to come back for a second interview, which would be even more technical. The second interview was an hour and a half long, and contained a lot of questions about cloud services. The technical interviewer was more junior and assessed technical talent by asking "Have you ever used [insert name of technology]?" over and over again. After those questions, a leader in the company asked a few good behavioral questions, and some personal questions as well. The interview was cut short, and I was only given enough time to ask two questions of my own. They stressed again that I would have very quick feedback the following day. Later that night, they asked if I could come in for a third technical interview, which would be "extremely technical" in nature. In the third interview, a senior engineer copied several blocks of code and asked me to debug them. It was a little hacky and the program they were using to execute the code was buggy and often broke, but I thought the questions were as good a technical assessment as I've seen - someone who is unfamiliar with the order of code execution would be weeded out very quickly. They stated again that I would have feedback the following day, and finally provided it through a recruiter. Overall, the communication was poor at best, and unprofessional at worst (they tried multiple times to skip over the recruiter I was working with and contact me directly, much to the recruiter's annoyance). They seem like they're still figuring out their process and communication for interviews. The technical assessments were hit or miss, some would give me confidence that they assess the ability of their engineers well, but the open ended "have you worked with X?" questions would not.
