Which short course helped you get hired? (update)

I saw that many postings ask for a specific certification. Any experience at all would help. I am unsure whether employers value it. Did a certificate help you get hired?

Check a dozen job postings first. If most ask for the same certificate, it is probably worth it.

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.
