There are two parts of Crossover. One is a regular offshoring, they hire underpaid developers in third-world countries, put spyware on their PC and force them to work long hours for peanuts. This is well known and I don't think anyone applies to Crossover anymore, unless they are fresh grads from Salvador or something.
But there is another part, which is far more funny! They find you and offer a position with a made-up title (SVP of technical something) and insane salary ($200 / hour!) - note that their recruiters are also underpaid slaves from third-world countries and they have their quota to fill or get fired, so they are very insistent.
As a part of application you have to pass a technical quiz, make some presentations, videotape yourself talking etc. Don't worry about this part. When you put it on a cloud drive, turn on tracking and you'll notice that nobody even opens your video or presentation.
If you do your technical quiz well, they'll try bait and switch - fail you quickly and offer a low-paid technical position. If they don't think they can switch you, you'll just become a number in their list of "top talents" they show to investors when they raise money to acquire one more dying software company.
Don't waste your time. There is no job.
