Stay calm and polite. Address the behavior respectfully by asking clarifying questions, keeping the focus on the role. After the interview, decide if this reflects the company culture and if it's a place you want to work.

Evaluating professionalism during interviews is critical. Strategic questioning helps assess soft skills, essential for organizational success. While technical skills can be trained, poor attitude and professionalism can harm reputation, especially in client-facing roles. I will address this behavior by asking appropriate questions that will help us to understand why the candidate is doing the same. I will indirectly give him an idea or hint by giving information of the company and asking some situational based questions and giving the candidate examples that his professional behavior is not good and as per the company's norms.

Stay Calm: Keep your cool. Address It: If something feels wrong, you can say, “Can we talk about my skills instead?” Think About It: If it doesn’t get better, think if you really want this job. Follow Up: You can tell HR about the interview if you want. Just trust your feelings and stay professional!

Maintain your professionalism. Take a deep breath and approach the situation with a clear mind.Determine if the behavior is a one-time occurrence or part of a pattern. Consider whether it’s something that could impact their fit for the role.Redirect the discussion to focus on the interview itself. You might say, “Let’s get back to your qualifications and experience relevant to this role.”Consider whether the behavior aligns with your organization's values and whether it would be a red flag in the workplace.

Staying composed and in control of course is a given. Unprofessional behavior can include a wide variety of behaviors. If it's something simple as being late to the interview or call, not apologizing, etc. I will set up a couple more calls to test punctuality and manners-see if there is a pattern to the behavior. If it's verbally inappropriate, I will keep my head, but I will handle it in the moment if need be. You never know what's happening in people's lives in that moment, so I would acknowledge it, be compassionate, but dig into it with them. If I continue to be dissatisfied with the behavior, I will make them aware and first use it as a coaching moment, unless it borders on a type of harassment. If that case, I would end the interview.
