If you're part of a good team, it can be a good job. There is autonomy within most teams, and after a certain point, the pay becomes good if you can stick with it long enough.

Corporate security and HR treat employees like children. The handbook says that good faith actions will not lead to retaliation, but this is not the case. The only way to dispute something from HR is to go through HR (guess what their decision will be?).

Re-orgs are frequent, especially when a new outside VP or SVP is hired. It seems almost mandatory that they shake things up, regardless of whether they need any shaking. Higher-level positions are almost exclusively filled by people outside the company, so upward mobility is limited after a certain point.

Many engineers choose to switch from the engineering track to the business track simply for more money. This limits the number of higher-level engineers. In fact, a few years ago, they refused to create any new high-level engineering positions. Imagine if they did that to the business track. They seem to constantly insert new engineering titles, which also makes it harder to climb the ladder.

HR complaints should not be handled by HR themselves. If a policy or law wasn't broken, then extreme punishment should not be taken.
