Alarm.com Software Engineering Intern interview questions

I had 2 back-to-back interviews with two different software engineers. First one involved a basic LeetCode question on making a queue with two stacks. Second one involved questions about OOP and threads.

Technical interview followed by phone interview with HR recruiter. Technical interview was fairly basic questions answerable in many different programming languages. HR interview was very impersonal, mostly asking what I knew about the company.
