Which short course helped you get hired? - what worked for you?

I saw that many postings ask for a specific certification. There are 3 people counting on me, so I am trying to be careful. I would like to use funding if possible. Did a certificate help you get hired?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

Thanks for writing this out. I went through something close to it 2 months ago, and it got easier once I kept a simple log of every call and form.
