This is a slight powerlevel on my part, but I have something to share regarding the observation that there is often a substantial mismatch between a jeet’s paper qualifications and their real-world performance. So, I have this jeet coworker, who by all accounts should be a subject matter expert and far more qualified than me. He has 10 years of experience on me and has all these letters after his name (we work in a field where professional licensure is not strictly required, but highly preferred if you really want to advance). Yet his project management style is incredibly haphazard and lacking in both basic communication skills and common sense. Also, when I look at the kinds of questions he poses to our clients, they are not any more insightful than mine would be—in fact, he often just compiles questions from myself and other colleagues, without adding much from his own perspective.
I do not think this is a case of fraud, as our firm is very meticulous about verifying employees’ credentials during its background check process. But I just don’t think I’ve encountered another situation like this where I was initially expecting to be highly impressed by someone, but then was disappointed after actually working with them.
