Answer: The best option for a handshake when introducing yourself to an interviewer is Option A: not too firm but not too limp.
A handshake is an important part of the interview process and can set the tone for the rest of the meeting. It should be professional, confident, and respectful. A handshake that is too firm can come across as aggressive or dominating, while a handshake that is too limp can be seen as weak or uncertain.
Therefore, it is recommended to aim for a firm but not overpowering grip when shaking hands with an interviewer. This shows that you are confident and capable, but also respectful and courteous. A high five or very light handshake are not appropriate for a professional setting like a job interview.
