A similar thing happened to my significant other taking a driving test. The state trooper said, "make a roundabout" and she didn't know what he was talking about. Both of us think a roundabout is a type of road layout with a big circle, not a u-turn as the instructor meant. So I know what you mean.
Programming job interviews vary wildly. Some people think you can't really judge a programmer well in an interview and are willing to give anyone who makes a good impression a chance. Others are grueling things which only those overqualified for the position would pass, and you will probably be suprised how often you get a call back from those.
