Vantaggi
People, freedom, vacation time, casual, can still make money in some departments (but that's changing). If you have a good manager, you'll have it easy. But managers change frequently.
Svantaggi
Anti-employee. People who sell well and use to make 170k a year are now making 40k. I'm not kidding; there is an IBJ article about it. It was basically a layoff disguised as a comp plan change, because everyone is leaving, but this way they don't have to pay severance like they did a few years ago with their last sales layoff. They keep "trying new things" and use it as a pretext to lowers the salaries of their sales force. Also, it's a lot harder to make the sale, goal are high and leads have been called constantly for years. Even well performing managers are fired because they are not liked by the right people
