First:

The thing that really made me disenchanted with the company came down to an incident where I replied back to a previous email chain with <REDACTED> (one of the higher-ups at Apple) with a topic that wasn't directly relevant to the subject of the previous emails, and then that asshole thought it was best to complain to every single manager between me and him, which was six people.

The next day every one of those managers decided to schedule a half-hour meeting explaining to me how inappropriate it was that I emailed <REDACTED> directly, instead of going through the bureaucratic channels. It was three hours of nearly-continuous meetings, all with the same subject of how bad it was to email a higher-up without first emailing every single person in-between first.

Three. Fucking. Hours. They wasted basically half a day just to make sure that I didn't send an email to the wrong people in the wrong order. It was worse than that scene in Office Space.

Second:

There was also another incident, where my manager's manager's manager emailed me, I hadn't replied in two hours, so he called my cell phone and yelled at me for not checking my emails more frequently. I tried explaining that email was asynchronous and that if he needed my attention immediately he should message me with HipChat or call my phone, which he clearly knew how to do, only for him to tell me that I have an attitude problem.

Not as bad as having my day ruined for emailing the wrong person, but still really rubbed me the wrong way.

There were a lot more annoying things that happened, and my understanding is that a lot of it was an issue with my team; Apple has thousands of software engineers and I think some teams are better than others.
