Hi! I'm Sahil Agrawal, and welcome to Decode with Sahil!
I've been preparing for software engineering interviews for almost a year now. In my journey, I've tackled over 250 coding problems and have interviewed with major companies across the US. This channel is where I share my experiences, the most important problems to focus on, and effective strategies for solving them-all in Java.
Here's the link to Blind 75 questions - which will help you understand important patterns to almost all data structures - leetcode.com/discuss/general-discussion/460599/blind-75-leetcode-questions
We will solve them regularly and get an understanding of important concepts
