Which short course helped you get hired? - any advice?

I saw that many postings ask for a specific certification. It has been weighing on me all week. I am unsure whether employers value it. Which ones are overrated?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.

Ask the course provider how many graduates get jobs and where. Honest providers can tell you.
