What to get into Options trading

[al4blink]

I have worked for two years in financial services consulting on back office engagements out of Chicago. I want to transition into options trading. I have started to look at some firms: CTC, Infinium, and Wolverine. Assuming I actually get interviews, what is the difference between these firms (all market makers i believe) and why type of questions would be typical of an interview, especially on the quant side. (what would be an example of probability and expected value questions).

Any help would be greatly appreciated

No, but I will certainly check them out.
