In defense of the recent guest, he said SOME firms don't consider PTO examiner experience to be that valuable, and that is true. He did not say it was a negative.
Axistek said that he wasn't even sure about doing IP law at all, and was wondering if examiner experience would help in any other way (e.g. as an engineer). And I would agree with guest that being an examiner would in no way help in general engineering or any other non-IP area. As an examiner, you do not engineer anything. You read big technical disclosures for form. Time pressure keeps them from truly learning the invention, so rejections are based on quick reads through similar looking prior art. There is no design work, testing, technical writing, or other engineering type activity as an examiner.
If you later decide to be an engineer, working at a non-engineering job would be a negative because you would be further removed from your school and have the same engineering experience level as a fresh graduate. You could go for the maturity angle and at least having work experience, but gov't work is completely different from working in a corporate environment as an engineer.
