Lets ask how hard it can be?
Seriously I heard, company where I work as part time repairguy, the most experienced and with most knowledge in house just quit his job, dunno why, haven't asked but now company is trying to find new guy trough work rental services and their recruitment advertisement ain't convincing me they know what they are doing.
Here is the recruitment ad and I have bolded the odd things

We are looking for our client a quick pace ASSEMBLER work on electronic component repair operations. Your work includes repair tasks in addition to quality control. You are repairing defective products by soldering and soldering products which are made during mass production. You're Needed to work in other manufacturing activities. In order to succeed in this job it requires dexterity, as well as the interest and enthusiasm for engineering. The benefits for getting the job are the experience of similar tasks and appropriate educational background (in example the electronics or precision mechanics). We appreciate that you would understand of electronic components and manufacturing, as well as electrical diagrams and -hierarchy literacy. We also appreciate the soldering skills as well as leisure-time activity eg. Small electronics.
Well this is google translation so its meaning is a bit twisted to more positive than original.
Basically they're asking for an assembler, not a technician / a repair guy who understands actually something.
Also you fix things by soldering and soldering? (original words: juottaminen and kolvaaminen. These are the same thing!). Also they are not saying minimum skills required, only asking it would be nice to know? Seriously.
I know what will happen, our executive vice president will bring again a new guy, that this here will be our best repairman (again?)

Seriously the last one he brought cannot even use his tools properly and it is painful to watch how he tries to look "busy repairing" by doing useless stuff he has no idea what hell he is doing yet he doesn't even ask for help

Basically job needs god-level skills of soldering with professional level solder stations, basically you need to be able to hand solder 01005 (imp) size components, able to read and understand electrical diagrams with radio technology, able to use oscilloscope and learn how to use computer assisted tools for repairs. Now if you're a pro would you apply trough "rental" place with these kind skills with this advertisement?
Well hand soldering skills for that component size can be trained but if you need to teach everything about repair, what is the point? He will able to fix only trivial faults like missing component or tombstone ones.
Edit: I blame management for not understanding what they are actually looking for.
