Microsoft

Benefits and perks are top-notch.

If you are young, you have a high chance of getting a job.

MSFT is doing great business overall.

There has been age discrimination from upper management/HR behind "attract young talents." Old people get laid off/fired easily (with reasons that don't make sense), and young people get hired easily.

Also, even though the CEO may be trying to change the culture, the workplace is still an old political battleground. It may depend on your manager and the division you work for. So, do your research if you are thinking about any position there.

I had some great years, but the last year, when I was managed out, defines the overall impression.
