Frequently asked questions

What does a software engineer do?

A software engineer designs and builds features for an application, taking tasks from requirement to working, tested code. They write and review code, fix bugs, work with databases and APIs, and own the features they deliver. They break problems into clean solutions and need less guidance over time as they grow toward senior roles.

What is the difference between a software engineer and a developer?

The titles are often used interchangeably in India. When companies distinguish them, engineer can imply a broader focus on design, testing and system thinking, while developer emphasises writing code. In practice both build software, and the seniority level, such as junior, engineer or senior, matters far more than the choice between the two words.

How do I grow from software engineer to senior?

Take on larger, more ambiguous problems and own them end to end, from design to production. Write clean, tested code, review others well and reduce guidance needed. Show good judgement on trade offs and help teammates. In most Indian companies, consistently delivering at that level for a few years leads to a senior software engineer role.
