I applied in-person. The process took 3 days. I interviewed at Ascend One (Columbia, MD) in Feb 2013
Interview
The interviewers begin with "Tell me a little about yourself and why you are applying for this position." They are really big on the "Tell me a about a time when..." questions. Make sure you describe the situation, explain how you handle the situation and the end result based on how you handled the situations.
Interview questions [1]
Question 1
Tell me about a time when you had to work with a difficult person.
