I applied through college or university. I interviewed at RSM (Houston, TX) in Mar 2020
Interview
I applied through my school website, interview happened on campus. It was a 30 minute interview with one of the partners. I received offer a month later (interview happened before covid).
Two round of interviews. First was with one of the RSM employees assigned to recruiting at my university. The second was a phone interview with a Manager at the office I was applying for.
The interview included 2 interviewers with at least one being a partner. Both interviewers were very friendly and set a calm tone that eased nerves. I would recommend relaxing and trying to get to know the interviewers as people to assess compatibility.
