As with companies that deal with public sector, the interview was a waste of time.
First of all, I was contacted by recruiter in LinkedIn, I didn't apply for a job.
I was clear in the beginning that after 8+ years of experience with AWS and kubernetes, (and 15+ in total), I would consider a position like this in order to gain Azure experience which is not on par with my AWS experience.
The position was just for CI/CD. No infrastructure, no kubernetes.
They hadn't even read my CV.
Total waste of time and one of the guys was rude as well because I asked for clarifications in one of their questions that was weirdly presented saying that I shouldn't ask questions because that way you force the interviewer to "reveal" the answer.
