Long, tedious, probably unnecessary. Took several weeks which is much longer than is necessary for that role. Overall it was a positive experience, but that may be because it was a positive outcome at the time

3 interviews in total. First was a brief screening with their recruiter. Very nice, pleasant. 2nd interview was with a sales team leader. I was instructed to make a sales presentation of anything I'd like. This took a few hours of preparation. Then a third interview was with that same team leader with a second team leader in which I made my presentation. I'm not a fan of companies requesting unpaid work from a candidate.
