I'd like to add to the previous postings on the subject:
1: Dress as though you were doing a F2F interview
2: Although, yes, you do get 7q's, and most of them allow you 3min to answer, you should know the following:
a: you get 30s before each one to prepare for it
b: You absolutely do NOT get the full 3min. Recording stops at approximately 2min50-55s, so plan on wrapping up with 5-10s to spare.
c: None of the q's are re-recordable. It's a one-shot deal.
d: You can wait as long as you like between questions, hours or days.
3: Expect to talk about your resume, in terms of what jobs you had, why you left etc. That was a tough one to cram in 2.9min for me (I'm an old git)
4: Be ready to discuss the 5 core values and how you represent them.
5: What would you change about your employer or your role there.
6: TMATT you overcame an obstacle at work

I'm sure there are others. Those are the ones I encountered.
Just did it, so I have no clue how I did.

Good luck, folks
