Reading through your comments/replies (e.g.: "knack for listening to customer", "generalist", "can setup machines"...etc) make me think I'll be in your shoes once I reach your age... Hence I have to ask - any advice you would give to younger self?

Should I focus on having some/one/few "unique selling propositions" - something I can say I'm expert in? And what would those be?

Anyway back to trying to give you (and other younger folks) some answers.

I've been interviewing candidates for a while. From technical phone interviews, over F2F, and now mostly so called Fit interviews.

And first time I interviewed someone with CS PhD that they have since around the time I was born - I was happy to be paired with another older colleague.

Not that I was scared/intimidated or felt inadequate. I was really worried about candidate getting impression we're a bunch of "teenagers" ;)

So actually on that point I've got nothing for anonOver60 - other than saying to others that instead of being intimidated, you should just be yourself and there is nothing to worry about.

If the candidate is good - being more experienced they'll know how to handle situation in a way that won't make you feel like 2nd class compared to them.

I second the idea of different/customized CV for different roles/positions. In fact each place/position you apply for should be it's own tuned/customized veraion of generic CV..
