Interview was online. Interviewers were friendly and it was not too difficult. The worst part about it was some buffering on the live feed, though the audio was fine. Sadly, the issue was most likely with the crappy internet service I had at the time. I wound up getting an offer, so it probably wasn't too off-putting.

Panel interview with three persons - plant, Corporate and another plant. Followed the STAR technique. Interview lasted an hour with ability to ask questions at the end. Interview was cordial.
