How to Format Experience Bullet Points (Before vs After)

Never just paste keywords into a laundry list. Use the Action Verb + Task + Impact Metric formula to prove your competency to both ATS algorithms and human interviewers.

❌ Weak Bullet (Lacks metrics and context)

"Built a machine learning model to predict customer churn using Python and Scikit-learn."

✅ Strong ATS Bullet (Keyword-rich with ROI)

"Trained and productionized an XGBoost churn prediction model across 2.4M user records, improving recall from 64% to 83% and preventing an estimated $1.2M in annual revenue loss."

Frequently Asked Questions

Are Generative AI and LLM keywords necessary in 2026?

Yes. Even for traditional tabular data roles, having familiarity with LLMs, prompt engineering, or RAG architectures signals that your skill set is cutting-edge.

Should I link my GitHub or Kaggle?

Yes, include a clean clickable link to your GitHub and LinkedIn in the contact header. Modern ATS parsers extract social and portfolio URLs automatically.
