I only had a discussion with one of their recruiters, who contacted me through LinkedIn. I am one of a handful of people in the area with extensive knowledge in my area of specialization. I had one past position on my LinkedIn that was less than a year in length. The recruiter asked about it in a pretty rude way. I answered truthfully but he acted as if I were lying to him and had a dismissive response. I then mentioned some things I thought were interesting about the role at Apple related to my work and he made some comments he does not have the qualifications to make or understand, and acted like I did not know what I was talking about. I've never had such a negative experience with a recruiter. This was a very unprofessional person. He then asked me to send a resume which was exactly the same as the information he had just asked me about. What kind of tech company needs someone to send a duplicate of information they have? I'm positive they know how to copy and paste.
