Software engineer interview questions for freshers
Fresher software interviews mix coding rounds with conversations about your projects and fundamentals. In the conversational part, the interviewer is checking whether you understand what you built and can explain technical ideas simply.
Practise these until you can explain your own project and the core concepts without notes. For coding rounds, keep practising problems separately — and talk through your approach out loud as you do, because interviewers listen to your reasoning.
Explain your final-year project.

What is the difference between a process and a thread?
What they are looking for: Operating system basics.
How to approach it: Own memory versus shared memory, cost of creation, and an everyday example such as browser tabs.
How would you find a bug that only happens sometimes?

How to approach it: Reproduce, add logging, narrow down the conditions, form a hypothesis, test it — and add a test once it is fixed.
Tell me about a data structure you used in a project and why.
What they are looking for: Applied understanding.
How to approach it: Name the structure, the operation that mattered (lookup, ordering), and why it beat the alternative.
What is a REST API?
What they are looking for: Web basics.
How to approach it: Resources at URLs, standard HTTP methods, stateless requests — then one example from your own work.
How do you use Git when working in a team?
What they are looking for: Collaboration habits.
How to approach it: Branches, small commits, pull requests and reviews; mention how you resolved a merge conflict.
Tell me about a disagreement in a project team and how it was resolved.
What they are looking for: Teamwork.
How to approach it: STAR, focusing on how you listened, what was decided and what the project gained.
What have you learned recently outside your coursework?
What they are looking for: Curiosity and self-learning.
How to approach it: A specific technology or concept, why you picked it up, and something small you built with it.
