I normally come across many advertisements about lecturership positions in different universities all around the world. And I always wonder when is the right time for a post doc. to apply for it? As, I am never sure that my experience will be enough for the position.

What are the necessary ingredients of a post doc.'s CV, that should help him getting such position?

In general, these ingredients can be found in the ads. as a vague statements like, extraordinary research experience, record of publications, etc. But what is the quantitative meaning of the qualities or does it just depend upon the applicants that applied for a specific position and their qualifications and achievements, i.e. a relative quantity?
