The way the outsourced companies are structured, the folks who actually know things spend all their time selling new customers/placating existing customers. The moment someone shows promise/that they are actually skilled, they get moved out of the actual dev teams.
This is the same on a lot of larger staffing agencies that promise to have all the people you need and can either do entire projects for you, or get you developers, designers, QA, project managers etc on short notice.
They have a few very competent developers who are primarily in the secondary sales in my experience. First sales contact is between non-technical management and their front-line sales (usually very attractive women). In the second sales contact, technical staff from the potential client is involved and they bring along their real developers. But those are not the ones you'll get on the project. They'll give you interviews with the developers you can get, and they're coached for the interviews and sound fine. But then in reality they are people who can't touch type and develop purely by trial and error without forming a mental model.
If hiring locally wasn't such a mess, nobody would talk to them. At some point even a junior developer is better than not having a developer at all. I assume AI will change that and they'll get replaced first.
It’s genius, in a way.
