Roscom Technical Sales Engineer interview questions

Invited to an Interview via a recruitment agency. The interview was arranged and I was notified that I would need to deliver a 20 minute "power point" presentation on Roscom, it's products and competitors. I spent 3 days researching the company and putting a the power point presentation together allowing myself a few days to finely tune and rehearse. The Interview was cancelled because apparently I lived too far away from their offices.
