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

I am considering a short certificate to improve my chances as a warehouse supervisor. I do not usually post, so bear with me. 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.

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