For stages process: HR screening, hiring manager, product manager, data science team. All the interviews (except HR) are built around experimentation. The last stages consist of case studies, with no technical or whiteboard questions. Everybody is nice and collaborative, although the whole process took a month.

It's roughly a 4-part process. There's an interview with the recruiter followed by an interview with the line manager/hiring manager. Then there's a take-home case-study/assignment followed by a wider discussion around that to assess technical competency. I was cut after the interview with the hiring manager and the reason given was that there were more competitive candidates available. I personally felt that the hiring manager had already made up their mind before the interview and that there was ethnic discrimination against me in the hiring process. For confidentiality i will refrain from discussing my and the interviewer's ethnicity. Overall the process felt like an interrogation rather than an interview.
