My Infosys Specialist Programmer Interview Experience – March 2025

Step 1: Online Coding Test – 3 Hours

My journey began with an online coding assessment featuring three DSA problems of increasing difficulty. The problems covered areas like Queue + Greedy, DP + GCD, and DP + HashMap + Prime Factorization.

Step 2: The Technical Interview – With a Live Coding Twist!

Unlike previous years, this time, the process included a live online coding assessment conducted at the Infosys Noida campus, directly in front of the interviewer. I was given 40 minutes to choose and implement one solution out of two coding problems presented (one involving DP/BFS and another on Binary Trees). Following this assessment, my interview commenced immediately.

Interview Breakdown:

1. Self-Introduction & PPT Presentation: The interviewer started by asking me to introduce myself and present my prepared PowerPoint presentation.
2. AI Specialization Discussion: Given my specialization, the interviewer was curious about why I chose AI, how I've utilized AI technology in my projects, and my understanding of core AI concepts with real-world applications.
3. Java Deep Dive: Since Java is my primary programming language, the discussion naturally progressed to OOPs concepts with real-world examples (I used a Banking System analogy), Interfaces in Java, Call by Value/Call by Reference, Memory Management, and a specific question about why Java doesn’t support Multiple Inheritance.
4. Internship & Projects Discussion: I engaged in an in-depth discussion about the projects I worked on during my internships and the technologies I used. Interestingly, for my personal projects, the interviewer was primarily interested in the problem statement and its real-world impact, rather than deep technical details.
5. Coding Discussion: This part focused on my problem-solving approach. I explained my solution and its time/space complexity for the problem I solved in the pre-interview assessment. I was also asked to write a recursive Fibonacci function and analyze its time and space complexity.
6. My Turn to Ask: I took the opportunity to inquire about technologies I should focus on before potentially joining, and the interviewer provided insights into current industry trends.

Overall, the interview process was structured, engaging, and highly insightful. The interviewer fostered a discussion-like atmosphere, which I appreciated. I am very grateful to Infosys for this opportunity!
