20 years startup/internet engineering here. I have "failed" roughly 50% of my interviews usually as the result of failing the coding rounds. Almost all of fails were conducted by someone with nearly half my years of experience who were interviewing for something from the CS academic curriculum. When I am asked to conduct an interview, I don't do anything much more complicated than a glorified fizzbuzz. I prefer doing architecture interviews. My biggest problem with algo interviews is most of them are trying to determine if you happen to be familiar with one particular algorithmic solution to something - if you don't happen to know that one algorithm, you fail. In the real world, you have to learn as you go. You never know the solution to every problem in advance.
