First step is a phone interview with a recruiter, followed by a phone interview with hiring manager. Once past this step, you are invited into an in-person interview with the hiring manager and possibly their manager. The questions are planned ahead of time and written. They do not deviate from the written questions. They make their decision after that interview and an offer will be made contingent on passing the drug test and background check. The background is the toughest as it can take anywhere from 1-4 months to finally begin work.
