As the candidate represents what he is, his values, aspirations, etc. the recruiter represents the company he's working for. Having extensive recruiting process steps, not replying to emails, being pushy, talking a lot - too much - , not following up, being vague about the next steps, not being respectful, etc. are all clues, almost evidences of how your future company will act with you in the future.
So, as a date which goes right or wrong, think about it twice before booking a second date. And as the recruiter has the right to refuse your application for absence of fit, you have the right to refuse the position for exactly the same reasons.
