Great question Jjemas
Although I can understand why it would be easier to start with a template, I firmly believe it is more effective to write it out yourself. I can't speak for everybody, but I can tell when I'm reading a filled-in template.
Writing a good CV doesn't have to be hard though! Start with brainstorming why you want the job. Then, write out why you'd be good for the job. There's draft 1. Next, do research by talking to those who work for the company, or online, about what skills and values the job is looking for.
Check out their website and find the words they use. Re-write your draft with that new information. Tailor your wording and information to try and get the reader to ask themselves, "why aren't they already working here?!"
Again, this is simply my opinion, but so far it's always worked for me! Hope it helps, good luck!
