Hi. I didn't face any DSA based rounds in internships. I have heard of it being part of full time fresher roles. I don't know much else about it.

I have been trying to build a chrome extension myself and I am a beginner when it comes to this kind of development since I majorly work in data science. This was a very good read!

yes you are right Nitin! Numpy provides various operations for multi dimensional arrays and other mathematical applications.
