I was approached via LinkedIn message by a recruiter. I had an hour phone screening/interview where I was then invited for an in person interview in Arlington, VA. The onsite interview consisted of 5 rounds of 30 minute interviews, followed by a lunch with the current START trainees, and then a mock sales interaction. The mock sales interaction consisted of an hour to research the data base for the answers to three questions. Then, you were invited to sit down with the COO and Director of Sales to pitch, handle objections, and close the sale. NO CLOSE, NO OFFER.
Even if you do not receive an offer (only 8 hired), it is a tremendous learning experience.
