About the Course:

Welcome to the Coding Interview Bootcamp with a focus on Python and JavaScript!

The primary goal of this course is to prepare you for coding interviews at top tech companies. By tackling one problem at a time and understanding its solution, you’ll accumulate a variety of tools and techniques for conquering any coding interview.

Daily Coding Challenges:

The course is structured around daily coding challenges. Consistent practice will equip you with the skills required for coding interviews and allow you to practice on Leetcode.

Topics Covered:

We start from the basics with Big O analysis, cover common data structures, and discuss real-life problems asked in interviews at tech giants like Google, Meta, Amazon, Netflix, Apple, and Microsoft.

For each question, we will:

  1. Discuss the optimal approach

  2. Explain time and space complexity

  3. Code the solution in JavaScript (you can follow along in your preferred language)

Additional Resources:

The course includes downloadable resources, motivational trackers, and cheat sheets.

How long do I have access to the course materials?
You can view and review the lecture materials indefinitely, like an on-demand channel.
Can I take my courses with me wherever I go?
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
