Fine-Tuning Job Readiness

After this lesson, you will be able to: Translate fine-tuning skills into resume bullets and interview answers for applied-scientist, ML-engineer, and research roles.

Fine-tuning is one of the most in-demand applied-LLM skills. This lesson packages your work for the roles that screen on it.

Prerequisites:Fine-Tuning Passion Project

Who needs these skills

Applied Scientist / Applied ML (adapting models to a product domain), ML Engineer on a modeling/post-training team, LLM/GenAI Engineer at startups, and research assistantships doing post-training. The common screen: have you actually fine-tuned a model, do you understand LoRA/QLoRA and the memory math, and can you evaluate the result without fooling yourself.

💡 Questions you will be asked

When would you fine-tune vs prompt vs RAG. Explain LoRA and what QLoRA adds. How much memory to fine-tune a 7B model and why. What is decontamination and why it matters. SFT vs DPO vs RLHF. How do you know your fine-tune actually improved anything. Each should be a crisp paragraph grounded in your own project.

Resume + portfolio signals

Best signal: a public Hugging Face adapter + repo with a clean recipe, decontamination note, base-vs-tuned comparison across seeds, and a limitations section. Bullet shape: 'Fine-tuned <model> with QLoRA on a curated, decontaminated dataset; +<X> over base across 3 seeds; adapter + recipe public.' The decontamination and multi-seed details are what mark you as someone who does this rigorously.

Common mistakes only experienced candidates avoid

Saying 'I fine-tuned a model' with no evaluation to back the claim. Not knowing the memory math (an instant tell). Confusing LoRA and QLoRA. Claiming RLHF when you ran DPO. Presenting a single-seed number as a result. Being unable to say when fine-tuning is the wrong choice, which signals you reach for it reflexively.
