I recently got lucky and made it to the technical round of an interview for a dream job with an amazing package. The catch? I haven't studied Data Structures and Algorithms (DSA) in a long time, and I've completely forgotten most of it. I only have 2 days left to prepare, and I'm really motivated to nail this round. Can anyone share effective tips or a quick study plan to help me refresh my DSA knowledge fast?

Check out the LeetCode Top Interview Questions study plan. It’s super helpful! Pick some key questions to work on, and if you're unsure about the solutions, NeetCode has great explanations on YouTube. Definitely try to learn how to implement some key data structures like Linked Lists, Stacks, and Trees. Also, familiarize yourself with important algorithms like Quick Sort and Binary Search. Just curious, how did you even land this interview without brushing up on DSA? That's surprising!
Consider pulling an all-nighter to cram! You need to go hard on this. Focus on practice problems that are relevant and don’t waste time on theory right now. Just get your hands on coding.
Thanks for the tips! As for how I got here, it’s a bit of a mystery to me too. I’ve been focusing on machine learning and AI, maybe they saw potential in that. However, the technical round is heavily DSA-focused, so I'm a bit worried!
