I've learned a bunch of things on the job:

- Picked up Finance on the go as it was required for the job. - Learned a lot about concurrency, java, python3, modern C++, React as I needed them to get my projects to completions. - Another thing which was completely orthogonal was political philosophy and it's interplay with economics, and to extend it further, behavioural economics. - Then there are soft skills like writing concise emails, presentation skills and general witty banter which I picked up as well
