So is "fake it til you make it" fraudulent or good advice?
Now I don't have to lie about my education. I would like to think its because of my skills I developed over 16 years but it could also be the times changing.
Like many here I also enjoy hobby development projects. I also suffer from imposter syndrome probably because to some commenters' point, I am an actual imposter.
So no, fake it till you make it, taken seriously, is not a good advice.
Also, sometimes pressure forces person to learn something in a very short period. So, if you "fake it", but also put significant effort to quickly learn what is needed to succeed then it is not lie but a 'future promise' it would be lie only if you don't succeed.
