I applied through college or university. The process took 3 days. I interviewed at HBL CPAs (Tucson, AZ) in Oct 2014
Interview
It was long: 3-4 hours total meeting with at least three partners, plus lunch. The firm has a total of 6 partners. Depending on what you want to do (tax or audit) will depend on who you want to interview with. If you want to work in both, plan on your interview to be a little longer.
Interview questions [1]
Question 1
Do you feel comfortable staying in Tucson for the foreseeable future?
