Royal Industries interview questions

Job description was NOT what they interviewed for. The job was for marketing, and during the interview, I got the distinct impression that the job was essentially going to be a Sales rep position. Everyone was really nice, but they also asked about things in my personal life, which seemed really weird.

An outside consulting firm does the initial hiring process, there would be two other interviews, which are even longer. The second one is video call, and the last one is in person, expect to last at least 3 hours.
