Lumen is essentially a Level 3 company that took it over after CenturyLink acquired it.
Upper Management most of the time does not even know the business of the department they are managing.
It was a diverse company with divers leadership when it was CenturyLink owned and managed.
Diversity is almost non existent now.
You can not even get a job in another department if you are a current employee and do not pass the robot interview. This includes if you have proven experience for the company. This happened to a former colleague that worked for Lumen.
