Landed a DE student job using Palantir Foundry but I have zero coding experience. Kinda panicking.

Hey guys, I read the wiki but have a specific scenario. I somehow landed a DE working student role for a major automotive firm (powertrain production). The stack is Palantir Foundry, Python, and TypeScript for dashboards. Full disclosure: I can’t really code. I’ve just been "vibecoding" with AI for uni. I have 4 weeks to go from "prompt engineer" to actually being useful. Based on the JD, I’ll be: building data pipelines, modeling complex manufacturing data flows, and creating dashboards to answer logistics questions. Since I can’t access Foundry to practice, how should I prep? Backend: With manufacturing/IoT data in Foundry, am I going to be using PySpark mostly, or just Pandas? Should I grind DataFrame logic or focus on SQL/data modeling first? Frontend: Is the TypeScript part in Foundry (Slate/Workshop) heavy coding, or mostly just gluing JSONs together? Survival: What’s the absolute 80/20 learning path so I don't look like an idiot who just pastes ChatGPT code on day one? Appreciat
