Programming interview is a winnable task. I will show you how to solve problems faster than you have ever seen before. I will show you how to think in order to solve difficult algorithmic coding interview questions that you have never seen before. You don't need any prior computer science training. I will quickly get you up to speed, skipping the boring stuff. Big O is the language we use to describe how long an algorithm takes. It is how we compare the efficiency between different approaches to solving a problem. It's like math, except that you don't have to worry about all the details and can just focus on what's really happening. We use big O notation to express the runtime as the ratio of the input to the output. As the input becomes arbitrarily large, it is called the "runtime".
