I applied in-person. The process took 1 day. I interviewed at Arc of Chester County (West Chester, PA) in Nov 2015
Interview
The interview process was laid back, straightforward, pretty easy. It was a one on one interview and she just asked questions she had written on a piece of paper. The person who interviewed me was friendly and she made small conversation about what she studied at school and why she decided to work at the Arc.
I applied through an employee referral. The process took 4 weeks. I interviewed at Arc of Chester County
Interview
Sent in resume and cover letter after job was posted and informed by a friend that was already employed there. Had 1:1 interview. The interview started a little late because interviewer was not ready. This was a very easy interview. Now there is at least one interview and maybe another round if necessary.
