I had two online interviews. The first one was behavioral: I talked about my background, my projects, and the reasons I applied. The interview is very relaxing and no stressful at all. The second one was technical: I was given a few hours to implement a small library. I had some difficulties in this last interview, but the interviewers were really understanding. I think they appreciated the way I explained my thought process and the way I critically examined my solution, admitting its flaws and how it could have been better implemented. So I was given a second chance to finish the library.
