Not recommendable
Arbeitsatmosphäre
Only one person in the whole company who can develop software by modern standards.
If you are a junior developer or tester then you will feel alone.
Kommunikation
Lots of talking but saying nothing.
Work-Life-Balance
The people are treated differently and not fairly.
Vorgesetztenverhalten
The higher up the superiors are, the more they behave strange.
Interessante Aufgaben
They have basically only three products. Neither the industry for which the products are developed for is interesting nor the way these products are developed and tested. Two of these products are over 10 years old and it shows.
Gleichberechtigung
Females are treated better than males. My personal experience was that for females every excuse was allowed to not keep the schedule, come late to work, or deliver terrible results.
Arbeitsbedingungen
Many things rather outdated. Software, hardware, everything.
A ping-pong table in a small room does not cut it.
Dirty floors and walls with stains everywhere.
Dogs in the rooms - not everyone likes them and it's not possible to complain about that because one of the dogs is owned by a superior.
People with allergies not saying a word because it's impossible to discuss this (or rather anything at all) with the related superiors.
Umwelt-/Sozialbewusstsein
All PCs are always turned on. All printers are always turned on. Lots of printing to then just throw the paper away.
That's the business there.
Company tries to counter this by supporting the employees in buying bikes but no one really believes that this is for climate reasons as the persons having decided that drive really energy inefficient vehicles.
Gehalt/Sozialleistungen
You get only paid well, if you're a freelancer.
Alternatively, you write so terrible code that no one but you can maintain it and then you can basically request any salary you want.
Looking at what I had to work with, it's quite clear that the highest paid people did this over several years.
The best thing in this company is that they are supporting you in moving to Berlin and finding a flat. Use that, stay in the company for 6 months and then leave.
Karriere/Weiterbildung
You will not learn anything there except for what you need to look out for in your next job interview.
