General Electric

Flexible and forgiving work hours.

Interesting technical challenges.

Close collaboration with intelligent people from other backgrounds (not software).

There is a great deal of technical debt, which grows relentlessly. I spent most of my time paying off this debt, none of which was due to me, and was never thanked. Staff (in the dev team) have seriously immature attitudes, and their actions can be ruled by emotions. You must use your emotional intelligence at all times.

The dev team is seriously deficient in teamwork skills and etiquette. The lead developers have little experience working in other companies. They have not learned to control their egos and have not gotten past the "I am a genius" phase. If a colleague does a good job, they will view it as a threat, become emotional, and attack them through covert means, including back-stabbing.
