Apple Program Manager interview questions

The interviewing process at Apple is excrutiatingly slow. However, I heard that once they made up their mind, the offer comes very fast. It took me about 3 weeks from the intial contact with the recruiter to personal interview. No phone calls from the hiring manager, it went straight to on-site interview with 3 different people. A word of advice I got from my contacts at Apple: loose your tie and jacket before the interview. Anything else goes,including T-shirt and blue jeans.
