Bloomberg Sales Analytic interview questions

I took the Bloomberg Aptitude Test (BAT), a finance aptitude test, nearly a year and half before I was contacted about this position. I had indicated when I would be finished with my masters, so they emailed me about this job. I had 5 rounds of interviews: 3 phone interviews, 1 video conference from the Paris office to the London office, and 1 in-house interview in London (final interview). I started the application process in June and finished the interviewing process in September. I believe it took unusually long and normally happens much quicker.
