> I got to a B2 proficiency level in around a year and to C1/C2 within a year of that

Congrats! This is no small achievement for a language not widely spoken outside of Europe. I went on a summer language immersion to Germany (living with a host family) and began picking up the language that way, in addition to listening to DW, radio, sports matches, etc. to get to that level. While I've only lived a small time in German-speaking countries, it's served me well with the some great conversations and connections at cultural and engineering-related events around the world, making life that much richer.

Anyways, sounds like linguistics might be your thing -- I'm sure you'll be successful at whatever route you go down.
