When I think about good and bad interviews that I have been involved in, it comes down to a few critical things on the business’s side. These are preparation, research, and attitude/caring. These things can make or break an interview not only on whether the company is good in general, but also the applicants view of the company and whether they want to work there based off of first impressions. If you have two equal candidates, but one interviews with the high energy and positive attitude that always wants to be successful, and the other one interviews with the manager who does the bare minimum and does not care about anything, if they offer both the job, who do you think is going to accept the position based off of first impressions. I have had several interviews where the interviewer seemed like they did not care about the position, myself, or even that they were there, and were often times belittling me during the interview. Even if I was offered the job, I often turned down these positions unless I really needed the job. This is where attitude and research come in. Attitude seems like a simple thing, but can be complex during the interview depending on the person. However, always being energetic, interested and invested in what the candidate is saying, and being thoughtful and meaningful in your responses shows that you are giving them the time of day and giving them a great first impression. Research is also important to find the right candidates to interview and to gain more insight into them. Assessments, virtual interviews, social media, and job example games and tests are becoming increasingly more popular with business for good reason. Just like it is important for the interviewee to research the business prior to the interview to be able to interview correctly, it is important for the business to gather as much information as possible using all these resources about the candidates to tailor the interview to them and get as much from the responses aqs possible.
