From the blog of fellow philosopher Keith Wayne Brown:
Cafe Terrace, Place du Forum, Arles by Vincent Van Gogh
…for the most part… philosophers aren’t deploying their firm grasp of Kierkegaard in their private-sector work. Rather, it’s the skills that philosophers are trained in—critical thinking, clear writing, quick learning—that translate well to life outside of academia. As Zachary Ernst, a software engineer at Narrative Science, puts it, “As a professional philosopher, if you haven’t gotten over-specialized and narrow, then you’ve got really good analytic and communication skills. So you’ve got the ability to learn quickly and efficiently. You’re also in the habit of being very critical of all sorts of ideas and approaches to a variety of problems. And if you’ve taught a lot, then you’re probably pretty comfortable with public speaking. Those skills are very rare in almost any workforce, and they’re extremely valuable.”

I would, as an outsider, say that successful philosophers do have specific skills in unearthing hidden assumptions and anatomising methodologies. But the other virtues claimed for them are generic among sucessful thinkers of all kinds.
