Hirevue, super chill. All behavorial questions, none too serious. Compared to the other 3 companies, by far the easiest. Seems like they're looking more for people they like rather than correct or best answers.
CV, Test with some social, math questions, very few technical questions, and required to write an essay on a particular topic (Why you choose Tax...), final Interview with one HR and one Manager
I had a video interview online for the first round and two interviews back to back for the final round with a manager and partner. The questions were all behavioral, and for an entry level role it felt like they were evaluating culture fit more than anything.
