This course of mine on coding interviews is more geared towards beginners to intermediate learners.
In this course, I cover fundamental but important topics such as arrays, strings, two dimensional arrays, and the Big O notation.
It should also be a good way to brush up on your Python skills, too, since I use Python throughout this course.
