The article beable links to is pretty accurate. They asked a few other questions, which I understand aren't fixed ones; our reason for traveling to Israel, whether we speak Hebrew and where we learned it, whether we have family in Israel and did we see them. There might have been others. (I was kind of sleep-depped at the time.)

They didn't ask us to take off anything we were wearing except outer jackets for the metal detector (which was later).
