Common Questions

Questions before you start?

I have zero coding experience. Can I still learn data analytics?

+
Absolutely. Many of our most successful candidates started with zero coding background — from marketing, finance, operations and even teaching. SQL and Python are much easier to learn than traditional programming. Our beginner roadmap starts from absolute scratch. Most non-coders are writing their first SQL queries within 3 days.

How long will it realistically take to become interview-ready?

+
For complete beginners: 8–12 weeks of consistent daily practice (1–2 hours/day). For candidates with some SQL or Excel experience: 4–6 weeks. For those with some Python background: 3–4 weeks for interview-ready SQL + case studies. Consistency matters more than hours — 1 hour every day beats 7 hours on one day.

Is all this content really free? What’s the catch?

+
All the written content, SQL guides, Python tutorials, practice questions and the SQL compiler are completely free — no account, no email, no credit card. We make money through paid 1-on-1 mentor sessions for candidates who want live mock interviews and personalised feedback. The free content alone is enough to prepare — the paid sessions just accelerate your progress.

Should I learn SQL or Python first?

+
Always start with SQL. It’s required in 90% of data analyst job listings, it’s faster to learn than Python, and it directly maps to what you’ll do on the job every day. Once you’re comfortable with SQL (usually 3–4 weeks), add Python. The combination of SQL + Python covers 95% of everything data analysts need. Add one BI tool (Power BI or Tableau) after that.

What salary can I expect as a data analyst in India in 2026?

+
Fresher (0–2 years): ₹4–8 LPA at IT services, e-commerce, startups. Mid-level (2–5 years): ₹8–18 LPA at product companies and funded startups. Senior (5–8 years): ₹18–35 LPA at FAANG, Flipkart, Paytm-level companies. Adding Python + ML can add a 20–40% premium on top of these ranges. See our full salary guide for company-specific data.

Do I need a computer science degree to become a data analyst?

+
No. Many top companies — including startups and unicorns — hire analysts based on demonstrated skills, not degrees. What matters is your ability to write SQL, analyse data in Python, communicate insights clearly, and tackle business problems. A strong portfolio (2–3 solid projects on GitHub), good SQL and Python scores, and interview preparation matter far more than your degree.
