Sometimes I had, often it was just supervisor, manager, team lead. A couple of times it was a panel, which included co-workers, but in a panel you cannot expect to hear their true feelings. One on one with co-workers is best. Best is if you have a friend already working there who can give you the low down. One job I ended up not interviewing at, was because of their glassdoor postings. Those in most departments loved the place, but all of the IT posting were how miserable it was. Dodged that bullet.
