I applied in-person. I interviewed at Alarm.com (Tysons Corner, VA) in Jun 2026
Interview
3 step interview process. 1st was the recruiter, didn't really go into my work history. Next was a video interview with a senior manager. They seemed really big on ai assisted coding. The lat was a 4 hour in person interview with the first two focused on system design and the last a programing logic exam focused on c# Linq questions. I bombed that due to syntax which cost me the interview.
