Anyone using Copilot Studio for recruiting/staffing workflows? Looking for architecture guidance.

We're in the early discovery phase of a Microsoft Copilot Studio project for a recruiting firm and I'm hoping to learn from people who may have already gone down this road.

Current environment:

• Bullhorn (ATS/CRM)
• LinkedIn Recruiter
• ZipRecruiter
• Indeed
• Microsoft 365

The business challenge isn't really "AI" itself. Recruiters spend a lot of time:

• Researching companies
• Finding contacts
• Searching for candidates
• Gathering information across multiple systems
• Updating ATS records

We're evaluating whether Copilot Studio could create a recruiter-facing assistant that helps search, summarize, and aggregate information from approved sources.

We're trying to understand supported approaches involving APIs, connectors, integrations, middleware, etc. I'm already checking out some stuff with a company called Zapier. I'm also studying Copilot Studio as far as creating custom workflows, agents, etc.

A few questions:

1. Has anyone connected Copilot Studio to an ATS/CRM such as Bullhorn?
2. Are you querying external systems in real time, or syncing data into Microsoft first?
3. Are you using middleware (Zapier, CData, custom APIs, etc.)?
4. Any lessons learned or things you wish you had known earlier?
5. If you were starting over today, how would you approach the architecture?

Not looking for someone to design the solution for us. Just hoping to get pointed in the right direction by people with real-world experience. I've always been the type of IT guy who is a 'jack of all trades'. I'm not afraid to learn and dive into advanced configurations.

I sincerely appreciate any info provided and your time for reading this post. Thanks much!
