I can understand a personality fit problem, but complaining about 'the right experience' is nonsense. Look for flexible people who can solve problems and they'll pick up whatever your flavor of the month is. Has hiring really come down to stupid HR lists? Must have 3 years of X and 2 years of Y. Please. You should be looking for problem solvers, not people who fit some arbitrary magical list. Yeah, it's harder to evaluate for 'smart, flexible' person than to scan a resume but the result is much better.
