Real, anonymous reports from people who interviewed for Research Analyst at Costar Group, newest first and distilled into what to expect across the loop.
I started with a recruiter call where we went over my background and made sure I understood the role and what they expected day to day. The whole tone felt professional and friendly, and the questions I got were fairly straightforward—mostly about my experience and how I think about accuracy, communication, and handling incomplete or conflicting information. After that, I moved into a more direct interview with the hiring side, and they emphasized that I should be comfortable talking in detail about my prior work.
My process dragged on far longer than I expected. It stretched across four stages over about two months, and one panel interview ended up taking something like six hours. To make it worse, a panelist didn’t show up, and that absence forced the schedule to shift into an added stage.
