Course Description

This course has been designed to help you pass your next coding interview. It focuses on puzzles from Codility's training lessons, so if you have an online coding test coming up, this course is perfect for you.

The key to passing coding interviews is to practice as much as possible by solving various types of coding puzzles. In doing so you sharpen your problem solving skills and eventually you will start to see patterns amongst the different coding solutions. You also increase your chances of being asked a problem you’ve already solved.

In this course you’ll get to practice many of these coding puzzles. In every section we introduce the topic, explain the problem and later provide you with a few hints that help solve the puzzle. In the end we arrive at the solution together.

Along the way you'll learn how to ride a motorbike, surf, scuba dive and fly an aeroplane. *

Join me on this course, and let’s get you to pass this interview!


*Not really, however this course is pretty fun regardless.

Yeh. It's absolutely very good content, loaded with information. I watched this in October 2024. Only 18 problems have been discussed here, whereas I can see more than 40 problems present in the cordiality lessons. It is my request that you try to cover all these and update the content.

He tenido la oportunidad de valorar este curso hasta la sección 10 y puedo constatar que tiene calidad en la explicación y en las soluciones que el instructor propone. Estoy satisfecho al 100% hasta el momento.

Very well produced course. I will probably never encounter any of those problems in my job, but I got into the problem-solving mindset with this course and got some needed refreshment on some of the concepts.

Very useful and good taught course. James is also very responsive and takes the time to answer any questions you might have. Much appreciated!

this course is amazing, excellent work and explanations

By Natalia Marek on 10/18/2020

Problems that James prepared are incredibly well explained with animations and analogies. New content is added to the course but at a slow pace (~30 mins of content every 2-3 months). Just don't expect that every Codility problem is explained here and you won't be let down. Also, James is very reliable in terms of answering questions. He responds to every question with great detail and care.

This is a great course! not even just for Codility but just for understanding core concepts when it comes to problem solving. I could barely answer any of the questions, didnt know where to start or how to even properly approach a question, given its wording. But by following this course ( for 2 days ) I found im able to understand problems a lot more, I really like the way you describe each question and show visuals and really solidifying what needs to be done before jumping to code. Its allowed me to complete the tasks in both C++ and C# as it doesnt really matter the language as the explanations are great! Thank you! Would love to for more!
