Overall, I had a very positive experience. The process was a bit long (a little over a month), but it also included the Easter holiday period in Europe/Montreal.
The process was: HR phone screen, hiring manager interview, take-home assignment, technical round, and three virtual onsite rounds (Product, Behavioral, and ML knowledge), followed by the final decision.
There was only one coding assessment, in take-home format. The algorithm/design pattern/GitHub parts were quite basic. There was also some web development content (CSS/HTML layout), which was more challenging for me since that is not my primary area.
I then had a technical round that focused mostly on past experience rather than the take-home assignment itself.
In the virtual onsite rounds, the last ML round covered many ML topics. I prepared a lot and was able to answer many of them, though not all. The interviewer was very helpful and willing to share knowledge, which I appreciated.
