Ask HN: interview with a "deal of the day" company

I am a new university business grad interviewing for an account manager position in one of the bigger deal of the day sites. I have two years experience as an account manager during my university career with a small internet based web development company. My job was to source clients who needed a website designed or redesigned and negotiate a deal to fit their needs. I was also the facilitator for communication between the client and the programmers and in charge for taking payment etc. I was responsible for coming up with new ideas for the company to make money (apps, blog networks etc) - We built these up and would sell them often within 3 months of launch. This is the only related experience I gained during my university career aside from doing the general landscape, campus jobs. I have always been very entrepreneurial building and flipping websites throughout high school and into university.

I am wondering what to expect in the interview. The job entails inside telephone business to business selling, cold-calling, prospecting, negotiating and closing business at owner level. I am to meet with the recruiter who will be giving me an overview and then will meet for a one on one interview with the sales manager.

I will be researching the industry throughly and figuring out the leaders, how this company differs from the rest and where the company fits within the industry.

What type of attire I should wear? (it is an internet based company) What types of questions will I be asked? What type of compensation is fair for this position? ($40k-$50k base + commission etc)

Any other tips will be greatly appreciated.
