Extremely rude HR. I removed myself from the interview process because of how hostile she was. Also, $145k package for a senior position is not competitive at all. A highlight of our conversation was her saying that "You have to tell me your expected remuneration and that's what I put in - you can't negotiate afterwards". If this is how the company representative behaves, it does not bode well for the company.

First stage was a phone interview with HR, followed by an interview (virtual) with the data science manager. I was then assigned a task (implementation of recommender system on a Kaggle dataset), which I presented to two Data Scientists from the team. An offer was then made afterwards.
