I applied online around mid-February and about 3-weeks later I got an e-mail saying they wanted to move along with the hiring process. Another e-mail was sent to schedule a 1-hour video interview with them a week later, saying there was going to be a moderator and 4 other candidates (engineers with the moderator) to interview me.
The interview was really easy. I've only had one "real" professional interview about 2 months before, and I've never done a video interview as well; my interview ended up being with the moderator and one engineer.
I was really nervous at first but they made me feel extremely comfortable and it turned into roughly an hour conversation about my resume.
It had the typical STAR-based behavioral questions, not necessarily technical but they will ask for experience and go in-depth about your projects in your resume so be sure to know every detail of your work. Obviously, don't embellish if you don't know the answer.
