Apple Data Engineer interview questions

Process started when I applied to the position online. Received an email from a recruiter followed by a call. She demanded to know my current salary which I wasn't crazy about revealing. Maybe they can post the salary range on the job description and not waste everyone's time? Either way, she scheduled a call with a hiring manager. The call was the typical, tell me about yourself, etc. Then went into some trivial database questions. Turning into a barrage of questions being pulled out of thin air. Then halfway between answering one of the questions (how do you do market basket in sql, something only mysql has natively) the guy says 'thanks, take care' and hangs up. This was followed by utter silence from the recruiter or anyone else. So if you like being treated rudely and have your time wasted, go ahead and apply here. They probably won't care either way.
