So many people place such a strong emphasis on their job title these, days and actually identify with as who they are. How many times do you ask a person what they, and all they tell you is their job title, not what they actually do.
The danger in self-important job titles, especially when looking for work, are that a title may have no relevance to the work you are doing and also, may be unintentionally misleading and prevent you from gaining even an interview.
Case number 1
A candidate applies for a job we have for sales rep, and his resume states that for the last 3 years he has been a sales manager. Most people would see this as a step back for the candidate and not proceed, but I met him, and it turned out he was the only rep far a small company in Victoria, and so simply had the title of Sales Manager.
Case number 2
Lady applied for an office manager role, and on her resume she had been an office manager, however, turned out she was only 18, and her cover letter stated “I have been office manager for my parents business since I was 12.”
Some job titles are so ambiguous that a person reading your resume quite often will not be able to clearly and easily understand what it is you have been doing in your current o previous role, so my suggestion is do not place such a heavy emphasis on your job title. It is not who you are, nor is it what you do.
