Echo Advertising interview questions

After a very brief phone conversation I was invited to meet with a hiring manager that week. I was informed that approximately thirty other candidates had been invited to meet with the hiring manager over that two day period. The interview lasted about fifteen minutes at the most. I was told six people would be invited back for the last round of interviews and that I would be notified that day. I was asked to come back the next day, which I did. I then met with a person who was "one of their best" salespersons, to discuss the details of the position and was further questioned about my qualifications. The entire process took less than five business days.
