Colloquio
I interviewed with AB in the Fall of 2020. It was by far the worst experience of my 7+ years career with a company.
First round with a fellow Data Scientist, it was not that bad, the guy was polite. Questions ranged from experience to drawing (virtually) derivatives, distributions, etc.
I passed to the second round where I spoke with what appeared to be a brilliant chief data scientist. In-depth questions, relentless back-to-back on various topics of ML.
Next round was with the CTO, which was extremely rude, not expressive and very vague questions around queries, that included live coding that I didn't do all that well.
All in all, I get the sense the culture in AB is not great and welcoming.
