I was initially interviewed over the phone. I was previously employed by labcorp so they not only interviewed my on the phone, but they called and verified my references. I was applying for an out of state job so the 1:1 interview was skipped (this is rarely done.) The interview took over an hour on the phone. The interview process consisted of a series of question based on previous experience and hypothetical situations. I was then asked to virtually walk through a draw. If the interview is done in person the draw is a live draw on the hiring manager.
