Contacted me through linkedin, for a remote position. There was no personal interview. Rather they send me a Machine Learning excersice that I had to do in a week. I did it, it was average difficulty. I got the RMSE to 5%, that was good enough for me. But they spend 2 months to review the solution, just to send me a generic email telling me there were better candidates. I asked for feedback and it was not given. I'am afraid they needed free work. For me it seemed a little bit weird. Because the spend too much time reviewing, there is no personal contact, they don't provide feedback and the excersice was easy to average difficulty.

Interview process is a joke. They gave a test. After submitting the solution, HR lady sent a mail saying, she will revert in a week. No response for 2 month. One fine day, she sent a congratulatory mail, saying I have cleared their test. Asked for salary expectation and scheduled second round of technical interview. Technical interview was substandard. Answered all questions and I got a feeling that interviewers knowledge in Data Science is limited. Somehow after a week of the interview i got rejection mail. So far I don't know why they rejected me. But I don't care. If I knew about them in advance, It would have saved my time.

3 step process - an ML test where they give you a database to work with; an interview with their senior data scientists; an interview with the CEO. Overall it was very challenging and enjoyable so definitely a thumbs up.
