Went through on-campus interviews, and invited back for an in-house interview. On campus interview was with a senior manager, and was pretty laid back and conversational. In-house interview was 3 back to back interviews with either a senior manager or partner at the firm. After the interviews, there was a lunch at a nearby restaurant with all the interviewees and a couple of the newer associates and senior associates.
Thought the interview went well overall, but never heard back anything from HR, not even a rejection email. In my opinion, it was pretty unprofessional reflected poorly on the firm to bring someone in for on-campus and in-office interviews, and not even bother giving them an email back regarding their decision. All other firms I had interviewed with during this process were able to give me a call or email back regarding their decision, and though the process did not work out smoothly for me at RSM, I was able to accept an offer elsewhere.
