Zoll farms out a 3rd party group, SRG, to interview you via the phone. The interview lasts between 40-45 minutes. It's a very rapid fire succession of questions that are both sales and non-sales related. I honestly thought I did well but apparently I did not meet the criteria of what they are looking for. I'm not sure what that is. I was honest with my answers so I'll just assume it would have been a poor match anyway. You would think 20+ years of medical device sales and sales management would account for something. Apparently not. I don't think there is anyway to really prep for the interview with SRG. Just be yourself and see what happens.
