Door Knocking

Visit potential employers without an appointment and ask if there is any work available. Your goal is to get an interview or other job leads and to leave a resume or calling card with the company. Like all job seeking you need to be prepared and create a good impression.
Always carry an adequate number of your job seeker Calling Cards and Resumes. You can leave whichever one is appropriate with the employer.
Take paper clips to attach a calling card or resume to any company application form. This will make your application "stand out in the crowd".
Be organised. Sit down with the telephone book and street directory and plan your "attack"
Be well dressed and groomed. You may get to speak with a person who can make hiring decisions. Even if you don't, the impression you leave at reception needs to be positive.
As with your telephone canvassing request an interview when door knocking. Ask about employment positions and other job leads. Ask to leave your resume or calling card just in case something comes up.
To get the right person or manager call just before or just after normal office hours. Sometimes the manager is in earlier or stays later than the other office staff.
Ask the switchboard operator for the manager's name and direct dial number.
If the employer is unavailable, try, try and try again.
