Tesla

A cool company with incredible products that are making a global difference. Stock pay is fantastic. There are incredibly bright and hard-working, good people in this company, if you count out most of the upper management.

The hours you're expected to work are ridiculous. Tesla fires people all the time and often changes the organization on a whim, so you'll rifle through managers. Management works to pander to Elon, which is good because he's brilliant and because most of upper management makes decisions that would only benefit them personally, anyway. They'll let you go in a second; there is absolutely no job security here, and it shows time and time again. Not a career job. If you come to work here, fight for yourself, fight for your teammates, but don't ever expect the company to care about you a bit.

Diversify the management set. Measure managers by how many people flee from their team(s) over time; there are a lot of those around. Stop fighting for yourselves and to make yourselves look good. Care more about the success of your teams, and Tesla will be better.
