Example letter

Dear Hiring Manager,

I am applying for the entry-level Data Scientist role. I have a B.Tech in Computer Science with a minor in data science, and I enjoy building models that are measured honestly and used in practice.

For my final-year project, I built a model to predict crop prices for farmers in my district using five years of mandi data. I started from a simple baseline, tried gradient boosting with feature engineering for seasons and rainfall, and reduced the error by 22 percent over the baseline on held-out months. I then wrapped the model in a small Flask app so local farmers could check the expected price before selling. I am comfortable with Python, pandas, scikit-learn and SQL, and I explain my results with clear charts.

Your team works on forecasting and customer analytics, and I would value the chance to learn from experienced data scientists while contributing from day one. I would be glad to discuss how my work could help.

Sincerely,
[Your name]
