There were two interview rounds conducted in one day for me. The first round, in the morning, lasted for about 40 minutes. After a basic introduction, I was asked to explain one of my projects in detail and the challenges I faced in completing it. Then, I was asked to share my LeetCode and GFG profiles, as well as my GitHub account, so my activity could be analyzed.

Next, I was given one hard LeetCode problem to solve, which involved sorting N linked lists into a single list using a heap. I was able to explain the logic and code it. The interview then ended, and I asked a couple of questions regarding the company.

I was selected for the second round.

The second round began with introductions, a discussion of my interests, and a light-hearted chat about my name. I was then asked to explain one of my projects and the challenges I faced, with some cross-questioning about my project. This segment lasted for about 20 minutes. Following this, I was asked to join a Glider link I had been shared earlier.

Two Data Structures and Algorithms (DSA) questions were then asked. They were not overly difficult, and I was also asked to explain their working and time/space complexity. I was then asked a question from operating systems about deadlock, which I explained. Afterward, I was asked to provide pseudocode. I was unable to write it completely but could explain my intuition.

Finally, I was asked a DBMS question regarding ACID properties, followed by an SQL query. This query involved an OUTER JOIN, and I was able to get it right on the second try. The interview concluded, and I asked a few questions about the company. The entire process lasted for a little over an hour.

Q1. What are ACID properties?

Q2. What is deadlock? Write pseudocode.

Q3. Merge N linked lists in a sorted order using a heap.

Q4. Explain a project and its challenges.
