The obvious is to have a neutral room, best is an empty wall behind you, that is quiet, nobody flushing the john in the background etc. You have that covered. Business casual is good too, definitely a shirt or polo, not a tie, not a t-shirt.

I would make sure you can see your image and be sure to smile / look friendly. This may be the big advantage of a skype interview vs. in person! You can see yourself and make sure you don't look grumpy, i.e. when asked a hard question that makes you think.

Dry runs with 1-2 friends is good input by others. You have to have the tech / software down 100%. Nothing is worse than a candidate fumbling with the computer / software.

Anything you can do to ensure your network is 100%, do it. Have a backup if possible, such as a phone's personal hot spot. Also test your backup with a friend.

Good Luck!
