Before the interview, I was approached by a recruiter about the job and screened to make sure I was qualified, then I had a mini-interview on the phone with a Costar recruiter, before the in-person one. The interview itself was quite easy - they asked very basic questions, and my doing research on the company ahead of time was overkill. I think I had more questions for them, than they did for me. The background check they that comes after though, is insanely invasive for an entry-level position. Not a position of authority, nor handling money, and they demand so much documentation for every single thing. Uneccessary and excessive.

Interview was first done via phone with a 3rd party recruiter, then followed up by another phone interview from someone at the company. After this, the final interview was done in person at a Costar office. The interview process was very smooth although they were a bit spaced out, but that is pretty normalized.
