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.
