📝 Round 1: MCQ Test

This round consisted of 29 MCQs covering Aptitude, OOPS, DSA, and C++. 📢 49 students were shortlisted after this test.

🔹 Round 2: Technical Interview 1 (Offline)

This round started with some introductory questions:
➔ Give your Introduction
➔ What subjects did you study in Information Technology?
➔ What is your favorite subject? (I said OOPS)
➔ From where did you learn OOPS? (Interviewer was surprised when I mentioned a PDF copy)
➔ How would you rate yourself in C++ on a scale of 1 to 10?

DSA & OOPS Questions:

1️⃣ What is pass by reference and pass by address? Write a piece of code for the same.
2️⃣ Conceptual questions on pointers and references (Some were tricky).
3️⃣ Write a code to find the sum of consecutive elements in an array, where the last element should be added to the first.
4️⃣ What are Constructor, Copy Constructor, and Destructor?
5️⃣ Does the compiler always create a default constructor? When is it mandatory to define one?
6️⃣ Explain OOPS features with real-life examples.
7️⃣ You are holding a pen in your hand. Can you apply Encapsulation and Abstraction to it?

🔹 Round 3: Technical Interview 2 + HR (Online)

For some students, this round was purely technical.

1️⃣ How was your day?
2️⃣ Introduction
3️⃣ Write a piece of code related to your internship in Notepad. (I wasn't expecting this, so I explained it at a high level and mentioned that I'd refer to documentation for syntax. The interviewer was okay with that and moved on.)
4️⃣ Write code to count the frequency of elements in an array.
5️⃣ Write code to find the missing number in a sorted and unsorted array.
6️⃣ Write code to find duplicates in sorted and unsorted arrays. (Initially, he mentioned that only a single duplicate was present, but later asked me to modify the code for multiple duplicates.)
