Hey there @Sourav3579 -- thanks for your post!

It is not possible to customize the booking flow that Calendly uses right now. This means that all invitees will need to head to your booking page, select a date and time, input their details and then confirm. Alternatively, you can use a routing form that directly routes invitees to a specific event type, but the invitees will still land on the booking page and follow that flow from start to finish. 

I’m sorry to disappoint! I do hope you have a good day. 

Thanks @Kelsi at Calendly for the reply.

Of course, @Sourav3579 - happy to help.
