All applicants must apply online, HR responds by phone. Initial phone interview is conducted by HR, vanilla questions about your experience, why you applied, basic weed-out questions. On site interview was 2 part with multiple 1-on-1 interview sessions (some positions do panel-style interviews), for this position, 2 interviews for the first on-site session, back 3 days later for a second session of 3 interviews. Each was 15-20 minutes long. Interview questions for the on-site focused on presenting a hypothetical & how you would handle it or how you handled X situation in previous experiences. Managers are very interested in your thought process, intelligence, and attitude rather than qualifications. Interviewers were friendly, but stern/serious, giving the impression that the culture was far more uptight than it actually is once you starting working. From application & interviews to offer letter was one week, background check took another week. Drug test is hair chromatography, not urinalysis, fair warning to any applicants.
