Screener interview, interview with supervisor, practical exam write-up, 4 interviews with team members. Overall not difficult, just time consuming considering how busy this time of the year is in the field. The interview process took 7 hours (with practical exam) and ended with no offer or explanation why. Followed up for feedback and never received an answer. Everyone seemed nice except for the the longest tenured interviewer that seemed to take exception to me bringing up specific work experience that he didn't have.
