Via Zoom, asked some questions, asked about my future plans, asked why I was interested in the particular team. Some whiteboard was used for me to explain my thinking to the interviewer.

Applied in early August and received an interview in mid-September for a September position...Should have known it was a red flag. After first round they seem impressed and asked if I'd like to do a "mini" project if I were invited to a second round interview which I said yes to. Got the questions, surprised by the number of typos in the questions. The workload was similar to a 2-month project I did at school when they said it should take me no longer than 3 hours, and I had to set aside a lot of your personal time to learn to pick up the basics. Then of course I wasted days of my life on this project, destroyed my mental state for that week and got rejected, no feedback provided, and they cancelled that second round interview (which was supposed to be the engineers reviewing my code and asking questions). I don't think they reviewed my work at all, no feedback upon request, just ghosted me after this. Not sure if it's just the team that reviewed me but it seems like there are other candidates on glassdoor who had similar experiences. Again, don't do unpaid work, it's not worth it.
