If we met for the first time and you were in an authoritative position (interviewer) I'd probably come off as timid because I'm reserved around new people, but once I get to know the person/environment and get a good sense of my limits/role/status I have no problem voicing opinions or dealing with assertive people. Just because I might seem timid initially doesn't mean I'm a pushover, and I don't think I'm the only one like this.
