Hubbell Graduate Rotational Program interview questions

I interviewed at a career fair for opportunities that were not yet known by Hubbell for an entry level mechanical engineering role. I got a phone call informing me that I was selected for a 90 minute in person interview 3 months later. Despite a 10 hour drive each way to the interview, I was not compensated for travel. I was not told which position I was interviewing for, despite requesting additional information weeks in advance. I discovered that I was interviewing for the Graduate Rotational Program upon arrival at the facility. In reality, I had 7, 30 minute interviews. I was informed that I would not be offered the position 6 weeks later.
