The rules for the capitalization of job titles are not very clear.
After I've read some internet articles (for instance, this Capitalization of job title question) I compiled some rules:
a) It goes before the name of a person:
Professor Adams or Director Joe Brown.
b) It goes immediately after the name of the person:
John Williams, Chairman, will attend the meeting.
Note: if it has "the", we do not capitalize: Mrs Smith, the chairwoman of the company x, is retiring.
c) In signatures lines at the end of a letter or email:
Sarah Stevens, President
But then, while browsing a well-known job search website I saw ALL the job titles capitalized in the jobs descriptions:
We are seeking to recruit an exceptional individual as Office Manager for the Registry team.
We are seeking to appoint a number of Teaching Assistants to support pupils' learning and to raise attainment.
and in a common English grammar book I see:
What do you do?
I am a receptionist.
Can somebody explain me the right to way to capitalize a job title?
