Initial phone screen. First round case interview, 1-hour, in-person. Second round three back-to-back-to-back interviews, 1-hour each, in-person. These varied between case, product, and behavioural. The case interviews are not standardised, even though HR supplies candidates with preparation materials to purportedly know what to expect. The interviewer style varied greatly from one round to the next, and whether or not you need to push through sections or allow the interviewer to guide was unclear. Even though the outcome was apparently known the day of the interview, HR waited 3+ weeks to share an offer decision. Feedback was not actionable, not very helpful, and somewhat contradicted what my experience was in the interviews. I was told the final decision hinged on a "feeling", not any measurable performance.
