In Germany that would be a recomendation letter, pretty much valuable by most HR departments, and not showing up with one isn't really recommended, a shitty one is better than none at all.
Yea apprenticeship certification is what I have (Germany). It's a lot different from other countries apprenticeships and shows ppl "Hey that dude worked this job for 3 years".
College degree should also work as you usually gather some job experience during university.
What i not meant were specific certificates like the Cisco ones.
Even a letter of recommendation from a previous employer would count for me.
