As I mentioned a while ago, I have never suffered from micro (or really, any) management. So I certainly never had a formal mentor relationship, one where I had regular (weekly?) meetings scheduled and some sort of planned progression.
Because of that, I've always found my own mentors. I badgered Technical Advisor when I was stumped on some of my analyses in grad school. And I've always worked with older geologists who were happy to
I've never worked with someone who I truly wanted to emulate professionally and personally. Instead, I've admired (and asked about) different facets - whether it's an amazing manager who knows a lot about the industry, a technical expert on something I'm interested in, or another female geologist who's overcome shyness to become a fearsome field lead.
With that said, I don't have any problem at all with a more formal mentoring relationship. I used to work with someone who did schedule a lunch date with me to discuss career advancement in the consulting business right after she was hired. I was a little taken aback initially, because that's not my style. But I was happy to oblige and we had a lovely discussion.
