The job seeker is the Product when it comes to finding a job. Quality is the first step that you want to display to the future employer. You want to tell him your strengths so that he is aware of how you will fit into the position available. In order to connect with he company, you should know a little history about it and what the position entails. This will give you a step up when competing with the other candidates.
Place is the next selling point in the interview. Tell the boss your schedule so that he knows your availability and how much you are willing to work. Place also involves a commute to work so make sure your geographical terms are reasonable. If the company is too far from your home, will your salary/pay be able to cover that drive everyday?
The third aspect of getting a job is Promoting yourself. You want the interviewer to know your best qualities. Make yourself presentable and dress the best you can. Always have a smile on your face and prove to him/her that you WANT this job. Make sure you always ask questions. This shows that you are very interested in the position that you are willing to learn more about it.
Lastly, be able to Price yourself. If the interviewer asks what type of wage you expect, unless it is a specialized position, give a reasonably pay rate...one you think you deserve. Price is an exchange for your service to the company so make sure both parties are being fair when coming up with that wage. If the interviewer gives a much lower price than you expect, maybe the job isn't right for you. However, if you think you can work your way up the latter, set goals for yourself and one day you will get promoted.
