OneSpan Customer Success Manager interview questions

Numerous calls with recruiter, 2 phone interviews, 1 F2F interview with Head of CS (supposed to be final interview), then called back for a 2nd (final final) interview with Head of CS and VP Sales. Though I had done a lot of research, the interviews were generally easy and more high-level about what customer success is on a daily basis. Quite conversational. Couple of questions around challenges facing financial industry around digital transformation. Quirky but nice enough London office. I generally liked the recruiter and interviewers. I didn't get an offer but my main sticking point were the reasons why - 1) unobtainable salary expectations and 2) financial experience. During the phone interviews it was made clear the salary expectations were obtainable, and financial experience was covered in no small detail, so it's a bit annoying these were ultimately the reasons presented for not giving an offer, especially after having been called back to another final interview.
