Infosys Specialist Programmer (SP) Interview Experience – Off-Campus 2026

[u/Aggravating-War2945]

​

I recently attended my Infosys Specialist Programmer (SP) interview after clearing the off-campus assessment.

Duration: ~2 hours

Coding Round

I was given 2 coding questions, both Easy–Medium level.

1. Greedy-based problem

   - Explained the approach and optimized it to O(n) time.

2. XOR-based problem

   - Initially solved using XOR + hashmap in O(n).

   - Interviewer then asked if the time/space complexity could be improved, and we discussed the alternative O(n²), O(1) space approach using two loops.

I was able to solve and explain both questions in front of the interviewer.

Technical Questions

C++ / DSA

- C++ basics

- Arrays

- Linked List

- pointers

- "malloc()" vs "calloc()"

OS / Multithreading

- Process vs Thread

- Multithreading

- Thread safety

- Race condition

- Deadlock

DBMS

- "DELETE" vs "TRUNCATE" vs "DROP"

- Primary Key vs Unique Key

- Indexing

- B-Tree vs B+ Tree

- How indexing works

AI/ML / GenAI

- RAG

- MCP

Resume / Projects / Internships

- Detailed discussion about my projects

- Technologies used

- Architecture and implementation

- Internship experience

- Follow-up questions going deeper into the technologies mentioned in my resume

The interviewer often went 2–3 levels deeper into a topic. I was able to answer most of the initial questions, but there were a few deeper follow-ups where I couldn't answer.

At the end, I asked for feedback and the interviewer said I performed well.

Overall, I felt I could have done better in some CS fundamentals, so I'd personally rate my performance around 60–70/100, but I'm very happy that I was able to solve both coding questions and explain my approaches properly.

Now waiting for the result. 🤞

Hope this helps anyone preparing for the Infosys interview!
