Yes, I was in an "agile" org that over-hired senior engineers and then expected them to just do regular "spade" work tickets.. but more quickly / more per sprint. No ownership of long running projects/tasks, no design/planning, just a constant stream of whatever ticket is at the top of the queue - GO.
Over the last 12 months, 55% of seniors have left. Most that remain have been at the firm 0-1 year.. The median senior now has 1 year on the team versus previous median of 3 years.
There's basically no institutional knowledge on the team anymore. Managers have now convinced themselves that all these green engineers are going to build v2.0.. however they are basically recommitting all the mistakes and suffering all the pitfalls that v1.0 did because.. no one is left to ask..
