HR called to see if I'm interested in the RA role rather than BA role. A case coaching session was scheduled that weekend. Two Mondays later, there was a case interview over the phone. Was called back for a series of in-person interviews and an IQ test the Friday of the same week. The following Monday, interviewed again at the local office. Three days later, went in the office one last time for a series of interviews. Offer extended that day.
