On-site interview at their London office. Had 3 interviews in total, 2 of them were video conferences. Each was 45 minutes. Everyone was very nice. They tried to gauge how much you know and if you don't know a particular area, they'll ask something easier. So it's hard to say how much I could have done more to land the job.

30 minute phone screen with HR, followed by an interview with the hiring manager. HR would not even provide a salary range for the role, which was very weird. The HR rep was not familiar with the role and seemed to be reading from the JD when I asked questions about it.
