These two remarks don't line up... They're a builder, all right, as long as you want them to build X. Perhaps they have been building X at some other company, and now your company has hired them to come and do that same job over here instead. Just imagine what companies would look like if their hiring processes filtered out this kind of charlatan The company specifically filtered them in to build the X product they're renowned for building at other companies. The hiring process is working perfectly if the company decides they want X, hires a famous X builder, and that person then builds X in their role. I think the point Rachel is alluding to is that the person should have realised X is inappropriate and said so, but if your world is X then it can be hard to see the broader picture. We've all tried to leverage the tools we know best to do jobs they're not perfect for rather than start from zero with something more appropriate, especially when there's a looming deadline or a lot of pressure from higher ups. To call someone a charlatan for doing that seems grossly unfair.
