I am new to database architecture though familiar with queries and aggregation in MongoDB.
At present working on a project where I have to store different user depending upon the type/role. There are few fields similar in the user model, would it be correct to create a separate collection for each role or just create separate schema then reference it i.e only a single collection.
In the future, more roles can be added with more information.
Any other approach is welcome.

Below is the mock models
Eg:
*customer =
{firstname,lastname,email,address,mobileno,password,role}
*sales = {firstname,lastname,email,address,mobileno,password,role,attachments,experience,
education}
*marketting =
{teamName,email,address,mobileno,password,role,members,attachments}
