Its a test given pre-interview to do in their time. 90 minutes, 3 questions. It is a gateway; candidates we want to interview a) can easily solve the problem and b) realise that its a 90 minute gateway test and therefore probably doesnt need to be gold plated. In baseline and control testing it has proven entirely effective in screening out the two extremes;those that cannot code and those that over engineer. (btw I agree with your overall sentiment; I put a lot of effort into making sure our interviews are friendlier, more effective and clear)
