Make sure that you do not place your elbows on the table in such a way that you appear to be resting your head on the table. This again is a position that is frowned upon in corporate meetings. In the same manner, do not put your hands under the tables as if you are hiding or fidgeting with something. If you are sitting in the interview room before the interviewer arrives, make sure that you do not slouch into the chair or sit with your legs crossed over each other. Your goal is to appear relaxed, yet dignified.
