Writing a CV

I’ve been working for the same company for the past 17 years. We have recently parted company quire acrimoniously. I’ve been out of the work loop for so long I haven’t a clue what is en vogue in how you present yourself anymore. I’ve lots of on the job experience and CPD training, so I guess I just need to bring everything together in a well presented CV. I’m out of work so need something that “pops” to get me a foot in the door at least.
