Inroads Mock Interview

So I recently joined INROAD and am in the process of become match ready.

At first I was told that I would have an in person mock interview, but then that got cancelled. I got moved to a video interview with a real person and was told that I should be prepared to answer technicals, but that also got cancelled. Now, I’m no longer sure what the mock interview is and how I can prepare for it. Does anyone know what the video interview is like? Is it prerecorded, what type of questions (behavioral/technical etc…)? Length? Do I need to specify my track of interest?
