Two 30 minute interviews back to back. The first one was a simple behavioral interview, and the next was a more traditional style, asking about strengths/weaknesses, etc. Overall it was pretty straight forward if you took the time to prepare. Still have not heard back.
I applied through college or university. I interviewed at Grant Thornton (Houston, TX) in Mar 2020
Interview
2 interviews, first one with a manger, second one with partner. Make sure to prepare ahead of time. They try to get to know you as a person and ask behavioral questions.
I applied through my schools career center, then a brief phone interview. I interviewed at Grant Thornton in Chicago by 3 partners for about 15 mins each. No technical questions.
