Had an initial screening interview, phone interview, then 4 in person interviews all same day. The interview process was detailed due to having 4 interviews in the same day however i knew i had the position once leaving the site.

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.
