I applied through college or university. The process took 5 weeks. I interviewed at CoStar Group (Arlington, VA) in Oct 2025
Interview
2 rounds: First Round is a Video/Zoom/Teams Screen with a Manager (They'll ask you questions about your resume, but it might be a vibe check, depending heavily on the Manager), and the second round is a Power Day. Also, for the first round, make sure you stand out. The Second Round is a Power Day interview. It is in person and 2 days (the first day is a casual networking-type event where you can meet some of your interviewers in a more casual setting, especially since you know who will be interviewing you ahead of time). The Second Day is the actual interview: two panels with two managers each (for a total of 4 managers, but one might bring along a SWE).

I applied through an employee referral. The process took 4 weeks. I interviewed at CoStar Group (Arlington, VA)
Interview
1 phone screen with recruiter. 1 interview with engineers, mostly resume grill. and then 1 on-site with 2 back-to-back interviews. All interviews were mostly resume grill- tell me about this project/experience. Be ready to go into lots of detail about each bullet point in your resume. The on-site was fun, everyone is really friendly and wants to see you succeed. On-site was the only technically challenging part, they will ask for specifics on REST and OOP principles and other things that is related to your projects & experiences.
