I got asked to interview at Abbott. They paid for my flight to their headquarters in Ohio, my hotel, and food. My flight was paid for upfront but my hotel and food expenses had to be submitted. It took them 4 months to refund me. The facility was nice and the people who interviewed me were nice. I did not get the job because I did not have enough experience which they knew from my resume so I'm not sure why they had me go through the process at all.
