I think that about a decade ago they still used horrible "why is manhole round" questions or "guess the trick" ones. The kind which puzzle-obsessed geeks like to ask eachother but which are horrible for evaluating fitness for a job. This changed. I interviewed 7 years ago and they have fixed this, judging by the questions I got and the interviewer training I received. Using trick questions and fixating on "the" solution was explicitly called out as bad. Of the questions I received two were open ended design questions and the rest was about algorithms and implementing them.
