I have to agree with this. If a company has 6-12 month projects using common tools, then the short-term stuff on a resume might be an advantage - come in, do the work and then (possibly) leave. Almost a consultant hire. However, if the environment has a steep learning curve or it's a multi-year project then yeah, it's a sign that the training costs might/will not be recouped. Different strokes for different folks - and I assume people choose their companies with more diligence that companies filter resumes?
