The way you put it, looks like IBM is a pretty good place to work at
I worked with some pretty talented and dedicated people at IBM. The “hop on a 2am call to put out a fire because they happened to check their email and they owed the person on pager duty a beer” kind of people.
That company was a red tape rats nest, but that’s management’s fault. And you get lazy people or shit departmental culture at various points in nearly every company, but painting a tens-of-thousands strong workforce with that brush is ridiculous.
