I think it can be tricky. We know the process doesn't always work. Some companies, e.g. Google, believe that it's better to adhere to a tough hiring process and reject most people even if a certain number of those people who are rejected may be brilliant engineers. But what I think is important to remember is that the goal is to hire the right person for the job. The hiring process you use may or may not be an effective and efficient means of finding that person. But certainly having a very narrow view, say by having a very strong focus on the process and little else, is a sure way to miss the right person at least some of the time.
