What do we know of Barney's occupation?

Question

In How I Met Your Mother, what do we know about Barney's profession except the fact that he works for GNB? References to the show (eg. "in Season X Episode Y,") will be appreciated.

Answer 1

From the HIMYM Wiki:

Not much is known about Barney's career.

However, it is known that he works for the AltruCell Corporation, then later Goliath National Bank after AltruCell acquires GNB in a hostile takeover (Episode 4x02: The Best Burger in New York)

• It is assumed that he is a high ranking member in the company.

• He has said that he knows so much about the company's dirty secrets, he won't ever be fired, (Episode 4x20: Mosbius Designs), although he was almost fired in the start of 2010 because he was blamed for the failure of a big merging. (Episode 5x14: Perfect Week)

• He was head of GNB's search committee in 2008 to design the new GNB headquarters (Episodes 4x08: Woooo!, 4x18: Old King Clancy, 6x03 Unfinished)

• His job also entails firing potentially hostile employees (Episode 4x18: Old King Clancy)

• It's hinted that his job may include illegal activities (Episode 3x14: The Bracket)
