Feel free to be economic with the truth by using aliases for organizations and products wherever it protects your privacy or your contracts. I’m mainly interested to hear about your unique experience.
Example follow-up questions: What was most rewarding, what was not? What was not a great use of your time but maybe still a learning experience? What were you interested when you were younger (for hobbies or otherwise) that may have helped guide you?
Like most here I work in IT. Unlike most here I have a BS in earth sciences (meteorology). While in school I did some summer volunteer work for the NWS near my home outside of DC that I found through an Alum that worked there. After I finished school that turned into a full time federal contractor position doing instrumentation testing and design. The facility was smaller and so I split my time with my friend (the alum that helped me in the first place) doing IT work. A few years down the road and I got a masters in information security (because sometimes a piece of paper matters). I turned that into a full time IT position at the same facility (still as a contractor).
For personal reasons I later moved out of state which was pretty difficult to find a job, most places assume you want relocation assistance or otherwise aren’t interested in out of state applicants. I used an employment agency to help, and got a good job as a jack of all trades IT admin at a small engineering company (about 200 employees total). I stayed there for a few years before moving to a large enterprise. I wanted to go somewhere with growth potential. I liked that job and made a lot of great friends and professional contacts. I ended up leaving for a verity of reasons (bad management, poor company outlook, and seeking more stability).
I eventually found my current job through someone I was working with who moved to my current company. I work for a national laboratory doing IT security work making good money in a super stable career (I’m a contractor so protected from a lot of the politics but the lab does work for the DOD so funding is never really in question).
My general tips would be:
