If that's true, then the interview process would focus more on skills. From what I hear, faang companies are all about the leetcode on the Whiteboard oh, and they don't seem to ask specific questions about domain knowledge. In fact, you often don't know which department or project you're going to be put on when you get hired by one of those companies. And apparently the interviewers don't know either.

At least a few years ago, Google made it a point that the interview process was generic, not specific to any position or team. More like an undergraduate admissions process.
