n8n interview questions, quiz and handbook in your Learning Dashboard
What you will learn
- n8n connects APIs with triggers, nodes and credentials, self-hosted or in the cloud.
- Code nodes run JavaScript or Python when built-in nodes are not enough.
- AI Agent nodes add LLM reasoning with tools and memory.
Glue code is still code
Every product accumulates integrations: send a Slack alert when a payment fails, sync new sign-ups to a CRM, summarise support tickets every morning. Writing each as a microservice is slow; scripts on a laptop are fragile.
n8n gives those jobs a home: a visual workflow with retries, credentials management, execution history and the option to self-host, so data stays on your servers.
In the rest of this story
- Triggers, items and expressions
- A Code node that cleans incoming items
- Keeping workflows maintainable
