Universal Events interview questions

After I did some research on the company and discovered they're just like Bay Inc. and other "Marketing Events" companies, I decided not to even go to the interview. Even though they advertise positions as "Marketing", that in itself is a marketing strategy because they are purely commission-based. Commission means Sales; Sales and Marketing are not the same. So although I cannot confirm that the position was a lie, it surely felt misleading when the job description said 1 thing and the fact that it's commission-based said another. The only positive thing I can say is that the girl that called was very nice and sounded very sweet and sincere. She was nice enough to be completely honest with me when I called back (after doing my research) to ask if it was commission-based. She saved me time, gas, and the upset feeling of being misled and having my time wasted; so I appreciate her a lot for that.
