Duo Security Software Engineer(Internship) interview questions

I was selected to interview for a specific team at Duo after going to the career fair and their office event post the career fair. I had a first technical phone screening which lasted for about an hour. After that, I was selected for an on-site interview at their office in downtown Ann Arbor which went for about 2 hours. 1 hour with 2 software engineers and 1 hour with the hiring manager. After waiting for a good period of time, I was extended the offer.

Sent my resume and got an email scheduling a technical interview. Two parts for the whole process. One is a technical interview over the phone and on coderpad, where they can see you code live. Second is a onsite technical interview.
