Which of the following is GOOD behavioral advice for an interview?

The advice to not sit until asked to do so reflects an understanding of appropriate interview etiquette and respect for the interviewer's space and authority. This behavior demonstrates professionalism and acknowledges the formal nature of the interview setting, which can create a positive impression. By waiting for an invitation to sit, you show that you are attentive and considerate, setting a respectful tone for the discussion.

In contrast, interrupting the interviewer could come across as disrespectful and may hinder the flow of communication. Speaking only when addressed may lead to missed opportunities to share relevant information about your skills and experiences, while answering questions as briefly as possible might prevent you from fully showcasing your qualifications and thought processes.
