It is too loose. In this instance it may be because "Berufe" is a noun while "employed" is a verb; being able to recognize nouns versus verbs can be important (e.g. you should capitalize the first letter of German nouns). In any case, DUO checks to see that you know exactly what is what (although that gets a bit difficult when things get idiomatic.) As my piano teacher used to say "First you show me that you can play this music exactly as written...and then, if you have a good reason to, you may play it differently."
"Employed" can mean simply occupied with some activity. I think this usage may date the person. I don't know anyone who uses the word this way, but there is the expression "gainfully employed," which means you have a job that pays. The expression acknowledges that one could be employed with some unpaid activity such as household chores.
