Data Analyst Career Guides
Breaking into data analytics as a fresher or a career switcher is a sequencing problem before it is a knowledge problem: which skills in which order, which projects actually get callbacks, and how to translate coursework into a portfolio a hiring manager will open. These guides are written by a founder who has reviewed 500+ data resumes on hiring panels, and each one answers a single real career question with a concrete next step.
What you will learn
- ✓Follow a 12-week roadmap from SQL fundamentals through to portfolio and job hunt

- ✓Build 3 projects that prove different skills instead of 10 that prove the same one
