Process took approximately four months from start to finish. Initially was reached out to by a recruiter, had initial phone screen, then a second phone interview, then a final interview. The process was actually quite lengthly, from the original time I was reached out to for the position, to the times in between. I was first approached about the position late 2014, and I didn't complete the final interview until this year. Received an offer letter very shortly after the final in person interview. Note: They DO administer pre-employment drug tests.
