Being prepared for an interview is not always easy. You think about the possible questions, you make a research about the company, you review your resume and you decide how much time dedicate to these activities; I know, looking for a new role is a job.
In order to be well prepared, you have to think about how/what you are going to answer. For example, you need to decide the level of detail that you are going to provide. When the recruiter will ask you a question you need to decide which details you are going to present… and you need to do it in a few seconds. You need to be ready to present cases or activities that you’ve completed/achieved or that are part of your daily job.
In most cases, our achievements and activities imply teamwork and shared responsibilities. However, even if it is important to show that you are a good team player, you have to present what degree of command you have for your activities. Showing accountability does not mean that you are not a team player. Mentioning only the activities that you are doing with the team is not enough to present your role.
