If you want to do this you need to decide you are going to go on the job market well in advance so that you can polish your 'job market paper'. This should be a substantial piece of research that is the basis of selling yourself. If English is not your first language it may be worthwhile if someone proof-read your paper. It is a good idea, if in the year prior to going on the job market, you take the opportunity to go to as many job market seminars as possible. It is also a good idea to meet and talk with any visitors from other departments.
Many students find their personal contacts very valuable in obtaining interviews.
The Department has a web page with details of all job market candidates. The Placement Director will do the cover sheet but you need to provide your own details. This should be done by the end of October. Prepare your 'Packet'. Your packet should consist of your job market paper, your CV and a covering letter explaining briefly why you want to work in the department.
