My first interview was with an HR employee who asked the normal basic questions, such as Why do you want to work for Speedway? The second interview was with the District Manager of the area I applied for and his questions were much more specific to work as a manager. The second interview was, in my opinion, the best because the interviewer was a genuinely friendly person who was simply trying to get a feel for my personality and abilities.
Whole process went very fast. Two days after I faxed my resume/application, I got the first interview. I went to the second interview 2 days after that. Less than 1 hour after leaving, I received the offer via phone which I accepted.
I wore business casual for both interviews (Button up shirt and tie with khakis and nice shiny shoes). I brought hard copies of my resume to both interviews. For those that need to know, there was no drug test. They don't do drug tests for any employees.
