The promotion track is strictly set on years of experience. They have released an initiative to help this by outlining a few responsibilities that one needs to take on in order to be promoted and officially changed the year requirement to "recommended." However, managers still treat promotions as a yearly requirement regardless of the responsibilities you take on or your level of delivery.
Instead of helping people grow quicker, they add more rungs to the ladder which keeps employees from reaching management positions for years and years to come.
If you are promoted from within, your salary will be less than the salary offered to external hires. I know a few external hires that were hired on with my job title 4 years ago at a higher salary than I have now after being promoted to the same position.
The starting pay has not increased at all in the last 4 years.
Resourcing is always difficult as we are a growing company. Though every time an employee leaves there seems to be a stress test on the team and no backfill position is created or it is created months after the fact leading to many months of taking on extra work to fill our contracts.
