It has three rounds. First round with HR, and then with senior members in the team, and the third round was with the hiring manager. People were nice, the questions were not difficult.

Applied directly online through their career page. Then, I had a brief phone call with the recruiter. Reached third-stage interview and each of the stages was with two different team members at increasing seniority (all interviews were online via Webex). I'd recommend that they apply more structured approach to interviews, with less open questions and less repetition. For example, at each of the three stages I was asked to go through my CV and relevant experience and if I knew about derivatives and option pricing theory. In terms of testing programming skills required for the role, they should have some separate tests and not just judging subjectively if a person has the skills or not. Last, but not least, it made me a negative impression that at the third-stage interview, one of the senior managers was having his lunch while interviewing me on the video call.
