I think my biggest ongoing frustration was how much time I was expected to read and reply to emails; on my first day one of the first things I was instructed to do was to use their internal email filtering system (the name of which I can't remember), because if you didn't you'd have literally thousands of emails going into your main inbox. Mostly alerts, lots of cross-team announcements that weren't relevant to me, some Radar updates on tickets that I wasn't assigned to IIRC.

Even when I got the filters more or less under control, I would still have to spend a lot of time replying to emails throughout the day, or risk getting in trouble for letting them pile up.

It was pretty depressing, and I remember the first time I pushed back I ended up kind of yelling at my boss's boss about it when I said something like "You know, during the interview you asked me a lot of really hard computer science questions, I thought that's why you hired me, but maybe we should revise the process to just be a fucking endurance test of replying to emails for two hours and see how they do." He didn't like this suggestion, for whatever reason.

So I don't completely blame them for saying I had a bad attitude, and frankly I don't think I was a good fit for the AMP team of Apple; I am far too unorganized.
