I attended the face to face interview for Campaign specialist after a phone screen with the hiring manager where we went in details through all my previous working experiences. Process was pretty fast: 45 minutes conversation with a member of the engineer team and other 30 minutes with 2 other representative of the company.
After these interviews I didn't get the offer because my knowledge was only about the Google advertising. This information was actually already in my resumee since I didn't have any other SEM experience if not in the Google advertise, so I really didn't get why they called me for an interview.
My experience wasn't good and the interview process was not professional, the explanation they gave me didn't really make any sense to me. Non raccomandable.
