An acquaintance recommended me. I was asked to send in a CV. After about a week, I got an email and they organized a screening phone call. I chatted for about 40 min with one of the backend team leads, it was a pleasant but technical conversation, where I described my previous experience. After that, we arranged for me to get an assignment. After waiting for about 3 weeks I finally received the assignment (I later found out that the delay was due to them having organized and attended a meetup). I had about 3 days to complete the assignment, which consisted of some general python knowledge, DB knowledge, and some matrix algebra. I completed the project, and then we went back and forth over my code, through comments on a GitHub PR. After they were satisfied with the code, we arranged for a group interview. It was a friendly but technical conversation. No live coding, hence the project was satisfactory. I had a couple of tough questions, general SE knowledge, and experience.
The process took 4 weeks. I interviewed at Crunch.io in Dec 2018
Interview
I had three hour long video interviews, met with 6 members of staff. They checked my references as well. I met not only with their recruiter but many senior team members and the president of the company. I finished interviewing and was told they wanted to check my references and took two and a half weeks to have three conversations. In the midst of this I was assured by a senior manager and the President himself that the entire team was enthuiastic and impressed by my interviews and candidacy. I had a phone conversation with the President as well on a Monday morning where said he and his team were actually putting together an offer, and asked what would I specifically need to join the team. He said he was excited to have me and would like me to start before the end of January. On Wednesday of the same week he called and told me they were going with another candidate, things change quickly - and that was it. I would not recommend that anyone invest their time with this team as they showed little to no regard for me as a job seeker, and acted contrary to what they would say or promise.
