Update the Google Calendar email, OpenAI and Google credential labels, system prompts, and branding as needed. Test the connections to ensure the API credentials are working correctly. Once everything is configured, copy and share the public chat URL from the Candidate Chat node. When candidates engage with the chat, the workflow will walk them through the interview booking process, check your availability, and finalize the booking automatically.\n\n\ud83d\udca1 Additional Tips\n\nBy default, the workflow avoids scheduling interviews on weekends and outside of 9\u20135 EST. Each interview lasts exactly 30 minutes, and overlapping with existing events is prevented. The assistant does not reveal details about other meetings. You can customize every part of this workflow to fit your use case, including subworkflows like Get Availability and check day names, or even white-label it for client use. This workflow is ready to become your AI-powered interview scheduling assistant.\n\nI\u2019m Robert Breen, founder of Ynteractive \u2014 a consulting firm that helps businesses automate operations using n8n, AI agents, and custom workflows. I\u2019ve helped clients build everything from intelligent chatbots to complex sales automations, and I\u2019m always excited to collaborate or support new projects.\n\nIf you found this workflow helpful or want to talk through an idea, I\u2019d love to hear from you.\n\n\ud83c\udf10 Website: https://www.ynteractive.com\n\n\ud83d\udcfa YouTube: @ynteractivetraining\n\n\ud83d\udcbc LinkedIn: https://www.linkedin.com/in/robert-breen\n\n\ud83d\udcec Email: rbreen@ynteractive.com\n\nRobert Breen\n\nRobert Breen\n\nRobert Breen\n\nDavide\n\nDvir Sharon\n\nLucas Peyrin\n\nn8n Team\n\nLucas Peyrin\n\nJimleuk\n\nOur customer\u2019s words, not ours.\n\nSkeptical? Try it out, and see for yourself.\n\nBuild complex workflows that other tools can't. I used other tools before. I got to know the N8N and I say it properly: it is better to do everything on the n8n! Congratulations on your work, you are a star!\n\n@igordisco\n\nThank you to the n8n community. I did the beginners course and promptly took an automation WAY beyond my skill level.\n\n@robm\n\nn8n is a beast for automation. self-hosting and low-code make it a dev\u2019s dream. if you\u2019re not automating yet, you\u2019re working too hard.\n\n@Anderoav\n\nI've said it many times. But I'll say it again. n8n is the GOAT. Anything is possible with n8n. You just need some technical knowledge + imagination. I'm actually looking to start a side project. Just to have an excuse to use n8n more \ud83d\ude05\n\n@maximpoulsen\n\nIt blows my mind. I was hating on no-code tools my whole life, but n8n changed everything. Made a Slack agent that can basically do everything, in half an hour.\n\n@felixleber\n\nI just have to say, n8n's integration with third-party services is absolutely mind-blowing. It's like having a Swiss Army knife for automation. So many tasks become a breeze, and I can quickly validate and implement my ideas without any hassle.\n\n@1ronben\n\nFound the holy grail of automation yesterday... Yesterday I tried n8n and it blew my mind \ud83e\udd2f What would've taken me 3 days to code from scratch? Done in 2 hours. The best part? If you still want to get your hands dirty with code (because let's be honest, we developers can't help ourselves \ud83d\ude05), you can just drop in custom code nodes. Zero restrictions.\n\n@francois-la\u00dfl\n\nAnything is possible with n8n.
