Is there a chance to get a job trough good connections in the dev world?
I know some guys, that are good friends of mine :)

Connections work in the job market. Why would the dev world be any different? But applying for one you're not qualified for - unless it's something you know you can learn and get the handle of pretty quickly - is somewhat sketchy imo. Where connections really make a difference is when there are several somewhat equal candidates - if there's someone speaking for you, and they know you're a good person, it's likely that you get the job instead of the next person.

don't.
Unless you are truly worthy the position you will be a burden for the team.
And if you're a good person you'll suffer from the impostor syndrome.

That's a loss-loss

How do you know whether you're worthy? Simple. Apply for the job via conventional channels.

aren't there apprenticeships as a informatiker in Germany?

totally. Some companies even offer reward for the connection that brought you in.

@heyheni yup, most definitely there are.
