A couple rules of thumb have been used to estimate the amount of time it will take to find the job you want. One is for every $10k in salary, it will take one month. The other rule of thumb is it will take three months of job searching 40 hours a week to find the job you want. The math equates to 500 hours of job searching. Further if we know about 10% of jobs get filled on the internet, then spend only 50 hours online. If up to 80% of jobs are received through networking, then spend 400 hours establishing, building and nurturing relationships.
