There are roughly four interviews. The first one with HR. The following with the HR manager (who has more information about the account), one with your direct supervisor, and finally with the portfolio manager.
It was an easy process for me, three interviews in total. They take a lot of time to get back to you so (2 - 3 weeks after each round) so I would be patient.
Nice 3 - round interview, pleasant atmosphere and relevant questions. It felt more like a conversation than an interview which was nice. The interview took place online with 3 senior specialists
