what should I do to succeed in my interview ?

I believe preparation is the key in an interview. Take your time to learn about the company and the job you are applying for. If you need to remember some topics related to the field, do it. Also, remember that one of the most important points in the interview will be your experiences, so don't save words related to your skills and experience. Finally, when researching about the company, make a list of questions that you have about the culture, opportunities for growth, and anything else you might be interested in. Overall, try to be calm and truthful.
