Best for

CS/IT students who like data, logic and systems more than pixels, and want a role where correctness and scale matter.

Maybe not for you if

If you want to see your work visually and care about design and interaction, start with the Frontend path instead. You will enjoy it more and learn faster.

  2. Phase 2 - Data structures and algorithms

    6-9 weeks

    Goal: Solve a medium DSA problem in about 30 minutes and explain the trade-offs out loud.

What hiring actually looks like here

Backend and full-stack roles are commonly reported as the largest share of campus software hiring in India, across service companies, product companies and startups. Most processes test DSA first, then core CS (DBMS, OS, networks), then your projects.

We claim no placement outcome, salary or success rate. This describes what is commonly reported about the role, nothing more. Linked resources are credited to their authors.
