What about timing?
As you progress in your field, it may take longer to find the "right" position, so don't get discouraged or jump into the wrong job. Also, be aware of specific peak recruitment times in your field, and plan accordingly. Remember, regardless of your field, for most companies, July / August and November / December are slow months for recruitment.
Most courses begin in September or October and recruitment may take place up to one year in advance, particularly where clearing houses are involved. If you are seeking funding, early application is likely to be beneficial. Go to I want information about further training or postgraduate study.
