Headland is a good place to stay while you're doing the interview. Easy access to Cathay and only a 2 minute bus ride to the MTR, or a 5 minute walk to Tung Chung.
Also made use of your secuirty pass and investigate all of Cathay City. Fantastic place. If you know someone there get them to take you around on a tour. Very interesting.
Good luck and be positive.
