# Overview

We are about halfway through the program which means you will soon be diving into your first technical interviews! To celebrate this milestone, we're going to take a brief detour and learn some of the most important concepts that you will encounter in those technical interviews. Data Structures & Algorithms is a fun chance to dive deep into code challenges!
