In this post, we'll be following the maxims of G. Oster) All coincidences are random, and the situations are fictitious)
Write the salary you dream of, and then add a couple of zeros to it. Forget the market - you deserve more!
If they ask for your full name - Write Vanya A.B. or Ivan or ivan3000, but never your full name.
If you've heard of names like Vray, Zbrush, Substance, or the mysterious Houdini - be sure to say you know these software like the back of your hand!
As a passport, you can attach a CV or spend time creating a PDF presentation - it's also part of CG.
Your portfolio is your gallery, your personal Tretyakov with a collection of works from your school days to your matured 3D wisdom. The number of projects will help draw attention. And to make life not so sweet for employers - seal your works in an archive and delete the link after sending - it's much more interesting that way!
