I didn't make the 3% cut, and had a pretty awful experience going through the interview process at Toptal. I was given a Euler-project type of problem that I had to live-code under a (I believe) 20 or 30 minutes. After I didn't succeed the interviewer basically hung up on the Skype call, and I wasn't really given any further feedback after soliciting it, other than 'you're allowed to try again after 30 days'. The whole thing seemed a bit ridiculous, as they approached me specifically for my (10+ years) PHP experience. I was told there was a lot of demand for it by their customers.
The Euler problem seemed to have a pretty low bearing on what most PHP programmers would do, so it all seemed super unfair. Had the challenge been anything related to API's, architecture or scalability I'm sure I would have passed. But doing math related to primes simply is not something that I practically ever need in my work so I was fairly dusty.
I would absolutely not recommend interviewing with them. Prepare to be disrespected unless you tick their specific boxes unrelated to the work you'll actually be doing.
