I keep hearing this but it is simply not compatible with my experience. Often the problems are given without any interviewer at all, for one (the initial screens). Even for ones where the interviewer is present, if I solve the problem, all is well. If I do not, all is not well. There doesn't seem to be any middle ground where I fail to solve the problem and it's fine.
