People claim all kinds of things as part of their resume and track record that aren't true. It's simply routine. People who were on a team that worked with a technology list their technology as something they know. People who were on a team that delivered a product claim the product delivery as their own. Drill into what exactly their role was during conversation and you'll get a much different story. Ask them details about the technology listed on their resume, and you'll quite often find that they know little about it. Resume inflation is so standard that filtering it out is not even a question. You know what's honest and true? Put someone in a room and talk to them, and see how they react to a situation and perform. See what they can figure out from first principles. Strong performance in these situations (problem solving, i.e. reasoning from first principles) correlates very well in my experience with strong performance on the job as a software engineer.
