To me, these are two different questions.
For the former, please see the 2 links below.

For the latter, similar to structuring a case, I'd suggest grouping your career into 'buckets'. As an example, here's how I do mine. Worked both in industry and MC. For industry, I sub-categorise into initial roles and senior mgmt. For MC, I talk about doing multiple workstreams on engagements, through leading project teams, to owning proposals.
In both cases, seamlessly add why you're a good fit.
Hope this helps.
