Infosys Interview Experience — 2 YOE

Sharing my recent Infosys interview experience for candidates with around 2 years of experience.

The interview mainly focused on my project, AWS architecture, Python, React, authentication, SQL, CI/CD, testing, and AI-assisted development.

Project & Architecture

1. Explain your project architecture.
2. Are you using Redux or any state management in React?
3. What type of database are you using?

Python

4. What is shallow copy and deep copy in Python?
5. What is map() in Python?
6. What is filter() in Python?
7. What are *args and **kwargs in Python?
8. Have you worked with Flask or FastAPI?

I was mainly using plain Python in my Lambda functions, and I had limited exposure to backend frameworks. The interviewer specifically suggested learning at least one framework such as Flask, FastAPI, or Django.

Authentication & Authorization

9. How are you authenticating and authorizing users in your project?
10. What is SSO?
11. What is OAuth 2.0?
12. What are the different types of authentication?
13. After authentication in the frontend, how do you verify the Bearer token in the backend?

SQL

14. Find the second-highest salary from a table.

AWS / CloudWatch

15. If there is an error in Lambda/CloudWatch, how do you resolve it?
16. Do you copy the entire CloudWatch error into an AI tool?

AI-Assisted Development

17. Are you using any AI tools in your development?
18. How are you using AI tools?
19. Are you directly copying the code generated by AI?
20. Once code is generated by AI, how do you verify it?
21. What limitations are there when using AI tools?

GitHub / CI/CD / Testing

22. Have you written any GitHub Actions workflows?
23. What CI/CD are you using?
24. Are you using Jenkins or Kubernetes?
25. Are you writing unit test cases?
26. After raising a PR, how does your lead review it?

What I remembered I am sharing

My Takeaway

The interview was heavily based on my actual project, but the interviewer also tested whether I had broader knowledge beyond the technologies I was directly using.

My biggest gap was backend framework knowledge. I was comfortable with Python and AWS Lambda, but I had not worked with frameworks like Flask or FastAPI.

The main takeaway for me is that having project experience with AWS and plain Python is not enough. I need to strengthen my backend fundamentals, learn a framework properly, and understand CI/CD, testing, authentication, and API development more deeply.

Sharing this in case it helps other 1–3 YOE candidates prepare.
If your company have any openings let me know.
