In this video, I conduct a mock Google frontend interview with a frontend expert, Conner Ardman, who's also the FrontendExpert course creator and an ex-Facebook software engineer. As a Google Software Engineer, I interviewed dozens of candidates. This is exactly the type of frontend coding interview that you would get at Google or any other big tech company.
Check out the Google Frontend CSS interview that we filmed on Conner's channel: • Frontend CSS Coding In...

In hindsight, I probably should have logged out the result of each of the transformation functions after writing them. It can be a good sanity check, and it helps make sure you don't lose the interviewer along the way.

My manager will write hundreds of lines of code before testing anything and he gets it 99% correct every time. He’s been doing it for around 8 years and the biggest difference between someone like him and a beginner is that they have a very strong understanding of how they are going to solve the entire problem from the beginning, even complex problems. Lots of beginners try to come up with the steps to a solution as they develop and will get confused because they don’t have a clear understanding of what their final solution should be.

In fact, I have been doing so at the different companies I have worked for several years. I would like to have a fighting chance by learning how to pass certain interview questions and this right here demonstrates that. If you find this unethical, then you should'nt be here. Have a Blessed day!

@Nikola B. Oufff This right here, what you have said "Can you at least treat me as a fellow human being and spit to my face without pretending you're kind?" why would I spit on your face when you were the one to come at me about ethics? I did not ask for cheat codes, so please do NOT imply that or, simply assume so. I am merely learning here as do everyone else who has positively commented on here. So yes, thank you, I will feed the right wolf that I choose. If you choose what I have said to be poison, then so be it. Your choice.
