The Employment History (or career history, work experience) section of a CV is a crucial part of any CV and as its name suggests: it is all about your employment history and the jobs that you have previously worked in.
Education vs. Experience is an age-old debate which has been going on for the past few decades and will most likely continue to be discussed for some time to come.
How can you get work experience if almost all the jobs require work experience before you start the job? It almost seems to be a Catch-22 (A dilemma from which there is no escape because of mutually conflicting or dependent conditions).
The first thought that crosses an employer’s mind when they spot a career gap on your CV is “Why is there something missing here?”
Being overqualified simply means that you are just too good for the job you are applying for. It means that you have received a lot of education and you also have a huge amount of previous work experience related to the job you are applying for.
Do you have to include a reason on your CV as to why you are leaving your current job? The answer is: no, you do not.
