Arrays, Linked Lists, Stacks, Queues, Trees, Graphs, Sorting, Searching, Dynamic Programming, Recursion, Hashing, DSA

This course is designed for students and professionals who want to land a job or get a raise by successfully passing top interviews that focus on data structures and algorithms.

In this course, you will learn the important concepts and techniques that interviewers often ask about. Whether you’re new to programming or have some experience, this course will help you strengthen your skills and boost your confidence.

You’ll engage with practical exercises and real interview questions to ensure you’re well-prepared.

In this comprehensive practice test series, you'll engage with five carefully crafted tests, each containing a variety of questions that cover key DSA topics and real-world scenarios. Our tests feature both multiple-choice questions (MCQ) and multiple-select questions (MSQ), with detailed explanations provided for every answer. This means you won’t just practice - you’ll learn and understand the concepts behind each question.
