I applied online. The process took 4 days. I interviewed at Krystal in Apr 2011
Interview
It took me a week to get his. Interview was short and sweet but thorough. They didn't miss anything. It was a fairly easy interview, since my aunt was manager.
I applied in-person. The process took 3 days. I interviewed at Krystal in Feb 2010
Interview
Very casual. Came in a couple of days after turning in an application, talked with the manager at a table in the store's dining area, and had the job within the hour.
