So, I'm just going to ask you a couple of questions. Have you created a resume from the job? (FYI: This is one of the most important steps of getting a job.)
If you have not I highly suggest you get one done as quickly as possible before the interview. Now, some question that will be asked in the interview are:
1. Why do you think you will be qualified for this job?
2. What are some of your qualities that will be beneficial to the job.
3. What are some of your strengths and weaknesses?
4. What is your objective while working the job?
5. Do you have any professional experiences?
6. What are some of your skills and abilities?
7. What are some of your hobbies?
(While at the interview it is EXTREMELY important that you get into details and explain when asked these or similar questions.)
