I applied in-person. The process took 4 days. I interviewed at Haddon Heating and Cooling (Concord, CA) in Feb 2012
Interview
Get a good nights sleep and ask yourself practical basic interview questions. That will give you the ability to use those questions you answered and apply them to similar questions. Other than that be calm, show that you are confident even though you are nervous. They want to see that you can perform under stressful situations that the position your applying for will throw at you.
