I had a phone interview with the hiring manager. The call lasted for about 40 minutes. The questions were part about my role, and the other part a little bit technical

Standard phone screen process. Call with recruiter to see if you meet the minimums, then a call from the hiring manager or equivalent a few days later. Flew down to in person interviews a few weeks later. Toured the operation (noted deficiencies that were asked about later). 4 person individual interviews. 1 Ops, 1 hiring manager, 1 equivalent EHS manager, 1 HR manager. Overall great experience, straightforward process.
