Several rounds that were spaced pretty far apart asking about typical work background stuff, then a trial of finding/fixing errors in sample documents. Four interviews total, three virtual then one in person.

First a phone interview, and based on that you will be chosen to go on an onsite interview. Mine lasted about 3.5 hours. I felt like they had already found a person for the position when I went, and I was just a process. They don't offer you anything to drink, and they won't send you a rejection email unless you contact them back. Kind of unprofessional.
