The entire interview process consists of a phone screen, meeting with hiring manager, coding skills interview, and system design interview. You can be cut at any point in the process.

The first step was a questionnaire form about your experience and why you want to work at Duo. The second step was a behavioral interview with the hiring manager. Be prepared for this as they are heavy on STAR format questions and will go into detail. Overall, everyone I met was very welcoming and nice. Unfortunately, I was ghosted after the second round and it has been about 2 months since.

Had 2 interviews. Took over a month to be able to schedule the first interview and then the coding interview. I had issues with their automated scheduler had a hard time getting in touch with a person to fix the scheduling issues. The first round was standard fare for interviews - asking about resume, experience, etc. They didn't inform me that the person who I had been scheduled to meet was not the person I was interviewing with. This is fine, the person couldn't make it, but some advance warning would have been nice. Prior to the second interview, they never sent a confirmation email (despite the first email they had sent discussing the 2nd round interview saying "hey look out for a confirmation email!"). I had issues during the first round with scheduling so I reached out to make sure everything was alright. I reached out to 2 different people multiple times over multiple days and only received a confirmation email an hour prior, so I wasn't sure if the interview was even going to go ahead. The whole process was such a pain. And during the second interview they said there might be 4 more rounds of interviews left! No thanks. Terrible process. Was not impressed with anyone who I interviewed with or was in contact with during the recruiting process.
