What is the bureaucracy in question? Required salary for the blue card is really low now, especially for tech workers, so basically you just go ahead and hire as I understand.
1. It takes forever to get a residence permit and get permission to start working.
2. It's increasingly difficult to find housing, which is required for the residence permit.
3. The bureaucracy is notoriously slow and outdated, and full of catch-22 situations. It's especially apparent when you need everything at once.
4. The language barrier makes everything harder.
In other words, if you meet all the requirements, you're looking at a multi-month slog before you're finally allowed to start working. People sometimes lose their job before they start due to the immigration office delays.
