I had a great phone interview with the hiring committee and was offered an on-campus interview a couple of weeks later. I drove the 5 hours there and paid for a hotel on my dime. The interview was conducted in the HR building and lasted 30 minutes total including the 5 minute pitch I was asked to prepare. I walked away feeling dissatisfied. I was not offered the position, but would have hesitated to take it anyway. That is not enough time to get to know someone, for either the employer or myself. If this search was just a formality for an internal hire, please do not invite graduate students and not offer reimbursement for expenses.
