Completed 5 rounds - recruiter was super nice and helpful in preparing me before each step. Ultimately did not get an offer because the hiring manager for one team did not think I was a strong enough candidate, even after passing all 3 of the technical rounds. Positive experience with recruiter but disappointed that one guy's opinion made the whole thing a waste of time.

It was a long process, many interview steps, many code challenges, but every one was very welcoming and kind. Sadly I didn't get an offer, they said another candidate had a bit better JS knowledge, so they continued with him.
