I've shadowed production stage managers in Chicago and Las Vegas. Shadowing has allowed me to know exactly what my goal looks and sounds and acts like, and that in turn has: first, let me know I'm on the right track; second, helped me identify areas where I can improve; and third, tweak my approach to my career. I am indebted to the generous people who've helped me so far, and I look forward to doing the same for other stage managers in the future. As far as resumes and interviewing goes, I've only ever provided my resume when asked. I do ask for advice, though, like "what kind of questions do you like an interviewee to ask you," "what do you look for in an assistant," "how do you avoid burnout," etc.
