They ask 10 question to write on a piece of paper and evaluating without understanding. After written exam next round was on Data Structure where interviewer was not aware about so many things, he was expecting exact approach which he knows and read from somewhere. I clearly understood, I was interviewed by a junior level tester or someone who was not aware about position for which he was hiring. HR was very sweet and helping. Goodera you should improve your interview process because this type of process is wasting your and candidate time as well.
