It's normal to feel a little nervous before an interview. Take a few slow, deep breaths if it gets too much and remind yourself that you've done this before and since then, you have acquired more experiences and developed existing skills. Prior to the interview, it's a good idea to do a bit of research on the following:
- The job description for the specific position you are applying for
- The vision, mission, and values of the organization
- Current issues, trends and practices that are relevant to the position
- The professional practice model/theory/framework used by the organization (if applicable)
Be prepared to talk about how your skills, experiences and knowledge can meet the position requirements, and that you are open to learning the things that may be new to you. Some of the questions they could ask you might include:
- What are some of your short- and long-term (career) goals?
- What words best describe you? How would your references describe you?
- Describe a challenging (work) situation that you have dealt with. How did you manage it, and what happened afterwards?
- Describe a situation that demonstrates your ability to adapt to changes at work.
- What are your strengths? Areas for development?
Plan ahead and try to arrive early. Also, you might want to bring an extra copy of your resume (and references) for you to refer to in case they ask you things about it. Try to stay calm, and do something fun/relaxing the day before. Keep in mind that the interview is a mutual learning experience. They need to figure out if you are qualified for the job meanwhile, you need to know if your needs are being met as well (i.e. opportunities for professional development; meaningful experience; types of resources and/or training you will have access to etc.). Anyway, best of luck and I hope you get the job!
