The entire process took about three months. It started with an HR call, followed by two semi-technical interviews with the manager of the team I would join. The questions focused on basic MATLAB syntax, despite the job ad mentioning that MATLAB knowledge was not required.

After that, I was asked to prepare a 40-minute presentation about past projects (who has time to do such a thing when you're employed?). This presentation was part of a 4-hour interview session. During this final interview, I was also asked to implement a hash map in a language of my choice.

I was then informed that the feedback following these stages was positive, and they wanted to move to the references stage before making me an offer. They required references from previous companies.

I was ghosted for a week after this. When following up with the recruiter, I was told there was a company-wide hiring freeze and that they would not be able to make me an offer at that point. Overall, it was a massive waste of my time.
