Samsung uses Codility.
I actually just took a Codility screen for the first time via Samsung. I really love Codility over the screen-sharing of other remote code screenings where it is awkward and somewhat traumatizing to have to code while someone is judging your work, especially if you stop to think for a while and don't want to think out loud.

That sounds pretty good.
The only problem in my experience with Codility was the way Samsung (and other companies?) was using it. I had 3 different problems to complete in 90 minutes and was not allowed to see my score at the end. I didn't get to attempt the third problem because I ran out of time on the second one (though I completed the first very confidently in ~20 minutes) trying to track down an error. A couple minutes after time expired, I received an email notifying me that I was not a fit for Samsung.
Oh well, if Samsung is looking for quick programmers predominately, then maybe I'm not a fit. And maybe the person responsible for letting all of memory be 666 is.
