Axelspace Engineer interview questions

Submitted my CV. Got asked to do a technical assignment. The nature of the assignment was such that you know if you've completed it correctly or not. Well, I did it correctly. It took a week and a massive amount of effort. "We've decided not to proceed, thank you for trying" and absolutely no further comments. Not acceptable.

1st interview with HR. Very professional, good impression of Company and HR after this interview. 2nd and 3rd interviews were supposed to be technical interviews, but.... IMO, there was a disagreement between the 2 teams for the job scope of the position and well, I think they have absolutely no idea who they want to hire. There was also an overemphasis on procurement and cleanroom work. Procurement was mentioned at least 3 times for a "technical" interview. Very bad impression of the technical capability/knowledge in Axelspace after these 2 interviews. They need to look at themselves to ask if they are hiring a technician, procurement representative or a technical engineer. This role was supposed to be very clear cut. Think traditional (mech/elect/software) engineering roles.
