Interesting in that when we vote for candidates we should be looking upon the past record and actions vs. what they say and promise. Although one can't predict the future, the past tends to be prologue...hence the resume. References should be a better window into performance but alas those are becoming meaningless and HR depts typically curtail anything of value. I think the interview is still a solid method (when done well). I for one do ask: "How do you stay current?" and am disappointed when told it is only through conferences, books and periodicals. Transparent PKM is key then to really seeing not only the product (a portfolio can do that) of ones work but more importantly the process.
