Many people who are going to a job interview plan too much and rehearse answers to questions, without actually thinking about what is most important to succeed in getting the job, according to Tina Persson, career coach and author of the book The PhD Career Coaching Guide .

- The most important thing is actually being able to explain why you want the job. You need to think about why you are applying for the job and what makes you unique for this particular position. When you know what your driving forces are, why you want to change jobs and what challenges you want to see in the new role, you become a more attractive candidate for the company.

Besides being on time, being aware of the dress code, being open and polite, there is one more important thing to consider.

- Many people don't think about the fact that the interview starts the moment you step into the reception or when you connect to Zoom. Many people forget that the small talk at the beginning and at the end is actually part of the interview.

What should you absolutely not do at a job interview?

- Apart from the obvious not to be late, be nonchalant or miss the dress code, an important point is not to talk too much. Remember that the interviewer is asking the questions - your job is to answer them, stay on topic and not ramble. As a recruiter, I have been around people who talked so much that I didn't have time to ask questions.

However, you are of course allowed to ask questions at an interview. Prepare three or four paragraphs that are relevant to the position and the company. But wait to talk salary until you've been offered a position.
