The most unprofessional HR I have ever experienced. Talked to them at a school-wide career fair, emailed them shortly after and heard nothing back for over a month. Myself and several classmates received a random call early in the morning asking us to do a phone interview that would lead to an on-site visit 4 hours away with only 3 days notice. Did not call them back. Terrible experience. Learn to set up interviews via email rather than randomly calling students at 9 am during the week. No excuse for that.
