I was contacted by the HR department to set up the interview and given the agenda for the day's interview. The schedule was from 9am - 11:30am and I met with 5 different people. I was given a tour of the facilities and plenty of freedom for breaks. Everyone was pleasant to speak to but post-interview I had very little interaction. I followed up with HR but never heard an official response about my position. I eventually determined they must have hired someone else but I was surprised that I was never notified, given how professional the rest of the process was.
