1st rd - manager
take home assignment video
2nd rd - panel
3rd rd - culture fit with manager's manager (I didn't make it to this stage)
Positives: Everyone was perfectly pleasant and personable.
Negatives: Manager in first call rambled and went over time, giving me not a minute for questions (didn't even clarify basic things like salary). Take home assignment was exhausting. In the 2nd interview, I was grilled about all sorts of specifics about the company/product, which I believe is unreasonable--have never seen that before or since.
