OK, I’ll play.
50 years ago - a lifetime ago - my first job out of high school was as a nurse’s aide while going to college majoring in biochemistry. Along the way, life intervened with my intent to stay in health care and I got a job with one of my hobbies - playing with radios - as an electronics technician. Eventually got promoted to test department supervisor and then they added quality assurance. Went back to the technician side after one of those early 80s layoffs. Spent from about '76 to '88 along that path, the last few while going to college at night (and reimbursed by employers) until I became an electronics engineer.
I have a checkered past for an engineer.
I worked for a defense/government contractor for a total of 12 years then went into civil aviation, designing radios for commercial aircraft. Small jets, big prop planes, and the big two in commercial jets, Boeing and Airbus. The first time I got onto a plane while on vacation and saw a radio I had designed parts of was kind of trippy. I designed the radio parts of systems for talking with air traffic control, VHF and HF, automatic landing systems, surveillance systems (collision avoidance) and weather radars.
At the end of '15, they made me an offer I couldn’t refuse to retire young - 61 instead of 65. Now I play with the hobbies I never had the time for while working; mostly ham radio and a home machine shop. Still play at guitar, still ride a road bike and do some other stuff, too.
