I worked as an intern at IBM last summer. It seemed like my entire team was a stagnant pool from the 70's. The languages were C and HLASM, 'high level assembler.' None of my managers knew anything about newer languages like Golang or Haskell. We built hash tables by converting strings to integers and then using modulus. They laughed at the idea of a Linux machine being useful as a server.

That said, most of the new hires were under 25, and most of the older people had been employees since the age of 25. But definitely the older people got all the respect.

IBM's full time offer to me was a solid 1/2 of Google's offer after stock and bonuses (over 2 years), with no room for negotiation.
