This type of thing happens with novice actors, new to the process, but even experienced actors need to think about orienting themselves in the audition process before entering the room. No one will do it for you. Figure out where you'll place the other characters you're talking to and place them near the lens of the camera so you have a good eye line. There will most definitely be a reader there (either the casting director herself or an assistant.) Some actors prefer to look at the reader, but it's not necessary as long as you have a good eye line near the lens.
