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.

All code in this course can be found on github, username/project: cutajarj/CodilityInPython

Who this course is for:

  • Python Developers about to take the codility coding interview
  • Python Developers about to take another coding interview, such as hackerrank or others
  • Python Developers about to take a face to face or phone coding interview
