Best advice I seen on CVs is as follows:
No more then 1 side A4. HR depts have not got time to read your entire life history. They dont care about your scouts badges and first aid courses.
Bullet points - Licences held, date of last IR, total hrs , hrs PIC.
Three to four lines on present situation - ie - working in ground handling, recently completed ATPL training, seeking first position. Strengths are etc etc
Give present employer and position, may 3-4 lines. Work history in further depth can be given on application form in due course.
Details of hobies/trip to the jungle etc can be talked about at interview.
Send CVs of every 3 months.
Just because an advert says minimum requirement are 1500 hrs tt, 737 type rating with 500hrs on type, send CV anyway. These are the airlines "ideal requirements". They might not find sufficient suitable applicants to fill the positions. Got this advice recently from my training provided. If you dont ask, you dont get.
