Make sure to dress up. They will send you around the office to interview with multiple employees who all will ask different questions. Be calm, cool and collective and you shouldn’t have an issue.
I applied through an employee referral. I interviewed at Whiting-Turner (Baltimore, MD) in Nov 2020
Interview
On Microsoft teams. Employees filtered in and out but conversation was mostly with two people. It was a very casual atmosphere with no real hard hitting questions. I think it was weird on both sides interviewing on teams instead of in person.
