What's the best format: chronological or skills/functional?

For all resumes, there is no “optimal” structure; it all relies on what you’ve done and what you want to achieve. If you’re applying to a more conservative industry (like banking) or continuing on a pre-determined professional path (like engineering), you’ll want to utilize a chronological resume. If you have limited job experience, are entering a field that is substantially different from your educational route, or are changing careers, a skills/functional CV is a good option.

Here are some websites to help you build a good and attractive resume.
