Frequently Asked Questions

What makes a good prompt?
A good prompt is specific, provides context and specifies the expected format. Instead of 'Tell me about marketing', write 'Give me 5 digital marketing strategies for a B2B SaaS startup with a €5000/month budget, in table format'.
Is prompt engineering a real job?
In 2026, it's become a skill integrated into most jobs rather than a standalone role. Knowing how to write good prompts is as fundamental as knowing how to Google.
