IBM

Generally viewed as a stable company that exists worldwide. They won't be going out of business anytime soon, and they are resistant to letting people go, no matter how underperforming an employee is.

Pay will be at the low end of the tech industry. The quality of skills is also low compared to other companies. People are not hired based on having good skills, or even the right skills, but more often just to get warm bodies to fill spots. This is very evident to anyone who has worked there for a long time. The quality of employees was much higher a decade or more ago. Not even close today. The fact that there are much better companies, and ones that pay much better, has resulted in IBM picking up the lower-end workers. It affects team morale and frustration levels, as higher performers have to spend most of their time covering for the lower performers.
