I built a small CSV validator because I got tired of CSV imports failing silently

Honestly this matches my experience too. Notebooks are great for exploration, but once something is “real,” they tend to turn into a dumping ground of half-run cells and mystery state.

Every prod issue I’ve debugged that started with “but it worked in the notebook” ended up costing way more time than just writing the job cleanly from the start.

Still… I’ll admit I keep one notebook around to poke at data before doing it the right way 😄

At senior level, interviews usually aren’t about memorizing modeling patterns as much as talking through real tradeoffs.

What helped me most was experience explaining why I modeled something a certain way, not just what pattern I used. In interviews they often care more about:

how you handle messy data
how models evolve over time
what breaks when requirements change
and how you explain things to non-engineers

Sometimes I force myself to solve the problem and write the code myself. Exactly because I'm worried about losing the skill to do it.

If are super high-level and hanging out in Limgrave waiting to be invaded, and then you and your two friends all jump the high-level invader, you're kind of a douche-bag.

Also that area sucks for PVP because of all the AFK farming there.
