I'm a tech lead, middle management. Only been here 7 months. Very very big company. Hierarchy wise, I report to a director, who reports to an svp who reports to the CTO. I can't see any path to promotion no matter how good a job I do. You are right in that knowing this is highly demotivational. I do get a variable end of year bonus though. Will wait to see how much that is before deciding if I'll stay or go.
