Interview Prep

Only 1 in 5 candidates pass the entire technical interview process at tech companies—their most common pitfall is the System Design Interview. When it comes to System Design Interview preparation, it's not enough to practice System Design Interview questions. This is because, unlike other technical interviews, there are many possible solutions to a given System Design problem. Rather, to excel in these interviews, you must be able to demonstrate the soft skills and thought processes that interviewers are looking for. 

In this course, you'll learn to master the behavioral aspects of the System Design Interview from a former FAANG engineer with 15+ years of experience designing distributed systems and conducting System Design Interviews. Whether you're interviewing for a role as a software engineer, technical project manager, or engineering leader, this essential System Design Interview prep course will prepare you with actionable best practices so you can confidently enter your next System Design Interview.
