A bunch of job search mistakes:

• Put your CV out on the web and expect that somebody will contact you based on just that.
• Your cover letter is mass-produced.
• Your CV includes every thiny thing you have ever done.
• You have not researched how the sector do recruting.
• Only applying for one job simultaneously.
• You are too limited in the geographical area you are applying for jobs.
• You are only applying for one type of job.
• You have lost your job in a losing sector, and then you are only applying for jobs in this losing sector.
