I am currently in my 4th year of BTech and have placements within a month. I am prepared with all the topics needed to ace the interviews and coding rounds like DSA, Projects, CS Fundamentals like Computer Networks and DBMS. I was pretty confused how should I spend this month preparing and what else am I lacking. Aditya Bhaiya told me to go with Object Oriented Programming and Low Level Design. These things I never thought of doing because most resources only talk about DSA only. His suggestion is to go with Object Oriented Programming in Java and correspondingly see some of the important and most commonly asked Design Patterns like Singleton Design Patterns. Along with this he also mentioned some good hindi playlists which he himself had prepared like from Shreyansh Jain YT Channel. I find myself lucky to have been introduced to Aditya bhaiya just before my interviews and would definitely go with Mock Interviews with him if possible and I get time.
