I have been contacted on LinkedIn by one of their recruiters. The first stage was a short informal chat about the role and my background. After about a week, I wrote to them saying that I was interested in the role so they sent an assessment about SQL without specifying the deadline. Due to some day of sickness I was not able to complete the assessment in what they later defined as a 4 days time limit. Because of that they preferred to not wait for the submission and just interrupt the process.

I had two phone interviews, one personal and one technical. I was then invited on site for a technical test, and was asked to build a deconv network in PyTorch. I had one more round after that that was higher level, and included an Hr interview. Ultimately was called days later and told I could not be taken on.
