🚀 HackWithINFY 2026 – Round 2 Cleared & Pre-Placement Interview Experience 💙

One of the most exciting interview experiences I've had so far! I'm happy to share that I successfully cleared HackWithINFY Round 2 and recently appeared for the Pre-Placement Interview (PPI).

Coding Round Experience

Round 1
Solved 3 coding questions based on:
- Arrays
- Greedy
- Dynamic Programming

Round 2
Solved 4 coding questions (Easy - Medium - Hard - Complex) covering:
- Arrays
- Trees
- Dynamic Programming
- Greedy & Problem Solving

The problems required not only writing optimized code but also handling hidden test cases and edge cases effectively. It was a great test of both coding skills and logical thinking.

Pre-Placement Interview Questions

The interviewer asked questions from both Computer Science fundamentals and aptitude.

1. Explain Operator Overloading with an example.
2. Difference between Primary Key and Unique Key.
3. Solve the classic 8L-5L-3L Jug Problem (obtain 4L and 4L).
4. What is Artificial Intelligence (AI)?
5. What is Machine Learning (ML)?
6. Types of Machine Learning.
7. Difference between Supervised and Unsupervised Learning.
8. Explain Object-Oriented Programming (OOP) concepts.
9. Swap two numbers without using a third variable.
10. Do you have any questions for us?

My Takeaways

One thing I learned from this journey is that DSA alone isn't enough. Along with problem-solving, it's equally important to have a strong understanding of: Data Structures & Algorithms, OOP, DBMS, AI & Machine Learning fundamentals, Logical reasoning, Communication skills, Confidence during interviews.

Every round challenged me to think differently and pushed me to become a better problem solver.

A big thank you to everyone who supported and motivated me throughout this journey. Looking forward to the final results and many more learning opportunities ahead!
