I applied online. The process took 2 weeks. I interviewed at Labcorp (Madison, WI)
Interview
Begin with a rep from HR contacting you and set up a time for a phone interview. The phone interview is quite standardized, they only ask a few questions and they are easy behavioral questions. If they want to go further with your application, you will be contacted by HR again and set up an on site interview, it's gonna be a 3 hour long interview with 3 managers, all behavioral, if you come prepared, shouldn't have a problem.
