1. In-depth questions related to your project. They asked about the architecture and design of my project. I was asked to draw the architecture on Ms PPT or excalidraw, 2. 3 easy coding questions. First was find duplicate in array. I told the approach using hashmap, sorting and nested loops, then I was asked to code it using nested loops. Second question was to check if a number is palindrome. Next question was to write a code in order to demonstrate Encapsulation. 3. In core subjects - OS --> Everything about deadlocks. DBMS --> I was asked what happens when you write a query in MongoDB, how it's exectued. Next I was asked to code a query in MongoDB. I asked to write it in SQL and I was allowed. There were 2-3 sub-conditions in the single query like finding a particular user and sorting their tweets according to date. OOPS --> I was asked about the pillars, real life examples of them, diff bw runtime and compilation, Then after 15-20 minutes I got the mail for MD round. Again I was grilled on my project. I was asked about the code of JWT. And how does google work. Lastly some questions as to whether I know about the company or not. Overall, questions were really easy. They kind of want to see how you perform in stressful situations. Even after being nervous and bombing certain questions, I got the role.
