A job interview is a recruiter's way of choosing from several candidates for the same position. If you won the interview, it's because your CV and cover letter convinced them to meet with you to assess you in more detail. It is important to know your CV well and to be able to develop on the qualities you have acquired during your previous experiences.
These may have provided you with the qualities required for this new position that you are coveting. Also prepare answers to standard questions. Evaluate your faults and qualities in relation to the position and make sure you can explain why you chose to apply for it. Also prepare your outfit the night before, choose it according to company codes. Generally, black and white work very well. Choose a shirt and pants or a suit skirt. Wear makeup discreetly.
Research the company and the position you are applying for beforehand. It is important that you are in tune with the values of the company and that you can demonstrate it. Do a search and remember the names of some important customers, the number of employees, the turnover and especially what is the news of the company. You can find all this information on the website. At the end of the interview, the recruiter will ask you if you have any questions. Do not hesitate to prepare a few, relevant questions will earn you points and show that you are a curious person. Be careful all the same to keep a little spontaneity and not to recite your preparation! Nothing beats being natural, even in a job interview.
