The Interview process consisted of 2 4-hour interviews. Meeting with roughly 3-4 people each time. The interview was fairly technical, although not overly so. Basic questions surrounding financial statement analysis and statistical analysis. With a focus on various credit metrics and regression types.
As far as HR goes, it was fairly unprofessional. They would go on radio silence in between interviews which was roughly 3-4 weeks at a time with no updates on progress or candidacy. After spending several hours interviewing, all I got was an automated rejection letter.
