Hello @Mansi Gusain , Thanks for using Microsoft Q&A Platform.
Yes, you can use Conversational language understanding (CLU). Looks like your use case is similar to Enterprise chat bot where it might handle frequently asked questions served by a custom question answering knowledge base, a calendar specific skill served by conversational language understanding, and an interview feedback skill served by LUIS.
Please go through this example usage scenarios to understand more about the CLU and choose the best model that fits your use case. You can use Orchestration workflow to connect skills together and appropriately route the incoming requests to the correct service.
Can I use conversational language understanding with custom question answering? You can use orchestration workflow to orchestrate between different conversational language understanding and question answering projects. Start by creating orchestration workflow projects, then connect your conversational language understanding and custom question answering projects. To perform this action, make sure that your projects are under the same Language resource.
I hope this helps.
Regards,
Vasavi
