Not too difficult, typical job for young people. Good starting point. Ask the basic questions like what do you like about whatever restaurant, and how you would work on a team, and stuff of that nature.
I applied in-person. The process took 1+ week. I interviewed at Doherty Enterprises (Newton, NJ) in June 2007
Interview
Nice People. Went in the store to pick up an application and then set up a second interview time. very quick and easy... personality test took a while though.
