It was a first round with the hiring manager who mostly asked behavioral questions. He described the role and what they do. Overall the questions he asked were trivial like bond market trading hours. I didn’t know about the sessions after the regular trading session.

One phone call with HR covering background. I was then invited for a technical interview online. I didn't pass the second stage so I don't know the next steps. For the technical interview I was talking with two quants.
