So, you have a video interview and you aren't really prepared for it.  Here are a few tips I suggest for setting up a video interview. 

First off, test it out in advance, the worse thing to happen is that it doesn't work when it's time and you end up taking 20 minutes trying to figure it out.  That definitely won't make a good first impression and  you're likely to be so nervous and flustered during the interview. 

So, to test it out, do it as soon as possible.  Test the following

1. Your mic - do you have a built in mic or a headset you can use?  A headset is best to tune out the external noises.
2. Your camera - Make sure your camera works. 
3. Positioning - it's best to position the camera so that you're looking as close to dead on as possible.  Anything between head and shoulders and mid-shoulders should be fine,  but you don't need to show your entire body.  You may need to use your outdated phone book, shoe box or something else to prop it up so you can see your interviewer eye to eye.  As a large chested woman, the worst thing is for the angle to be from the chest up, it is distracting for the interviewer and makes me feel very self conscious during the conversation. It's also awkward for other body types as well. 
4. Attire - make sure you're wearing correct attire from top to bottom just in case you have to stand up and get some thing during the interview.  The worst thing is for an interviewer to see pajama bottoms while you're chatting.
5. Lighting - Use plain lights, stay away from colors.  If you have a dark lamp shade, you may want to remove it and adjust your lights to a more neutral color. I have dark skin so sometimes lighting can be an issue for me.  I always make sure I have a good deal of light in the front of my face and not behind my face.  If you have lighter skin, you want to make sure the lights aren't too bright and wash you out.   
6. Background - Make sure that whatever is in the background looks professional.  A plain wall is fine, or even a closed door.  If you do have photos, just be sure they are tasteful. Make sure there's no visible piles of paper or trash in the view.  If so, move them to the other side of the room so that it can't be seen on a camera.

P.S.  If you're using a cell phone there are some great ways to set it up on your desk. You can use a few books to prop it up, or even make a cut out in a paper cup and flip it upside down to hold it in along with your cord.  There are several ways to be creative.  Be sure to test it and ensure in advance that it doesn't move around during your interview.
