It started with a HR call, followed by a take home coding challenge. I had 7 days to submit it. It was clear and had specific questions of what you'd need to do (for example: make plot showing X distribution over time). In the modelling part, they tell you the algorithm to use, which I think is a good starting point to guide your analysis. After submitting the challenge, they inform you if you've passed or not to the challenge review/technical interview phase. I moved on to the technical interview and it did not go well. As I was mentioning my challenge in my answers, I was told by the interviewer that he had not seen my challenge, only notes reviewing it. And so, we did not go through the challenge or mentioned it again. Instead, we focused on the algorithm they mention, specifically in its usage in the challenge's domain, and stood there for around 40minutes, with lots of theoretical questions.
My overall experience was good, except for the last interview. Maybe I was unlucky, but I felt he was a bit too theoretical and not letting me finishing my answers, which threw me off a bit.
I got informed I did not pass to the last interview step.

The recruitment process for this Data Scientist Gen AI position was excruciatingly long and poorly managed, stretching over two months. While I must unequivocally state that the HR representative was highly professional and meticulous, and the interviewers themselves were genuinely nice people whose conversations I enjoyed, their individual qualities were tragically undermined by a fundamentally flawed system. The process comprised an initial HR interview, followed by a burdensome technical assignment that felt like unpaid work, then two technical interviews which were frustratingly redundant, an HR culture check that felt intrusive given the lack of clarity on their end, and a culminating manager interview. This arduous, drawn-out process concluded with an utterly absurd and infuriating rejection, citing a supposed lack of seniority – a reason that completely contradicted my consistent transparency and candid self-assessment throughout all prior stages. This glaring inconsistency and inefficiency are a testament to their internal disorganization, not any failing on my part.

Typical initial screening with HR. The next step would be a technical challenge, followed by a discussion, then another technical interview and a final one for cultural fit. The interview was very normal and the interviewer provided broad information regarding the job without going into technical details.
