First call with recruiter took 30mins. Second call was with the hiring manager, who was friendly and seemed engaged. I was emailed a link to a coding challenge and given 45 minutes to solve a medium LC problem, followed by a couple of behavioral questions. The recruiter notified me the next day that I had made it to the next round; at this point, I asked what the rest of the interview process looked like, but didn't receive a response. The recruiter mentioned in the calendar invite that the third interview would incorporate React, HTML, and CSS. Because of this, I expected a machine coding problem. The third interview (with another engineer in the org) ended up requiring knowledge of vanilla JS, and definitely no React/CSS. The engineer interviewing was nice enough and helped me through with Google searches. I got rejected the same day. It would have been helpful to get a little more insight/accurate info regarding what to prepare for!
