This was my first exposure to a professional development job, but for medical transcription (we had a billing dept too). I wasn't even hired to do it (I was hired as help desk staff), but the application neeeeded updating and the 2013 HIPAA omnibus had just dropped so we were on the line to get in compliance and no one else was stepping up. I had to learn as I went. decade old, undocumented code written in old .NET and (some) Java 6.

No version control, running on Win2000/XP, ancient beige box hardware (some with turbo buttons).

I was 19 and making $9 an hour. I got fired for automating my help desk tasks so I could bring us up to date.
