IBM

If you are a go-getter and proactive about advancing your career, you will climb the ladder.

A key to advancement is working cross-team and with management several tiers above you.

Most of the time, you can pick your hours and work from home; it's extremely flexible.

There is so much entrenched bureaucracy; sometimes it makes you want to scream. There are definitely glass ceilings everywhere, and you have to know how to break through them or sidestep them. Make sure to negotiate a good salary. Every person is different and has a different salary, even if you are at the same band level. IBM runs on strict margins, so money can be tight, and even as a high performer, you often wonder if you'll be cut in the next round of layoffs.

Let us breathe between releases. There is no time to innovate!
