You'll start by getting an interview scheduled by HR. Nothing too technical you'll explain your resume and if moved on you'll speak with an employee in your role for your first interview. You'll get a technical test at the end of the interview, with very specific instructions you must follow, they will check time stamps on it. Hell more want to understand your thought process. Next you'll speak with the hiring manager, it's a false title he doesn't hire you and this interview is more of an interrogation where he'll pick your life apart. If you are "lucky" you get to move forward to another interview. The next interview will be with the technology officer, this was the most relaxed interview I had and was a nice change of pace. Unlike the hiring manager interview it was pleasant. Next HR will interview you again and contact references. Next you'll be interviewed again in office with the CEO. He was more concerned with another phone call than me at the time and unlike others who show their face on video calls he chose not too. A bit of warning is to do your homework on him, his Ted talk should speak volumes on his personality. Next you'll meet the data scientist, here is the make or break moment. He's basically doing an interogation, be very careful here as their is a possibility he'll decide to tell the owner things that are a stretch of the truth to protect himself. This whole process took 2 weeks it's very stressful and in my case I took a flight to NYC. If the scientist didn't stretch the truth too far you might get an offer. In my case I was told I wasn't hired over something I discussed in my final interview. Overall a very odd and paranoid experience.
