IBM

Good technical experience. A bit behind the curve, but in general, they catch up with the competition. I have had some nice workmates too.

The promotion system is based on self-promotion.

This has, over time, meant any decent management will just leave, leaving a complete set of people who are completely out of their depth and only skilled at self-promotion.

I have had a string of managers whom I either never dealt with or were completely incapable of doing anything.

I had one incompetent manager repeatedly defend a bullying team lead, as he had no confidence in getting anything done on his own.

Of course, this system leaves you no other routes open.

They are tied to this outdated, ridiculous bell curve system, which means each team has to carry a "deadbeat."

Promotions are rare and not based on ability.

To get promoted, people morph into... well, incompetent self-promoters.

The canteen is probably the worst in the developed world.

Office space converted from a factory; no natural daylight at all. A depressing space.

I only WFH two days a week to get out of that grim office.

In short, a dreadful culture, no career track, and some not-so-great people to work with. Managed by threats.

I'm extremely happy not to be working there anymore.

Get some backbone. Right is right and wrong is wrong, whether it's small or big.
