Waste of time. They don't read your CV. They just contact you and keep asking the same questions over and over. There is 4 interviews, one by email, one by phone 30 minutes, one by phone with a engineer and one on site. For a company that advertises using artificial intelligence and machine learning and having their engineers not knowing anything about it and saying that they don't use it, it is bad.

The first interview is via Google Hangout. There are two coding questions that you need to answer on a google sheet so the recruiter can read it meanwhile. After this, there is an onsite interview.
