Select all that apply. What types of data fit best in a custom object?

In the HubSpot Data Integration certification, product inventory entries, shipment information on a shoe order, and the interview stages of a hiring process are the correct choices because they represent distinct business entities that require their own unique properties, separate timelines, and independent associations with standard objects. Custom objects are designed for data that doesn't naturally fit into the contact, company, or deal schemas; for example, a shipment has its own lifecycle and tracking numbers that must associate with multiple contact or deal records, while a hiring process involves structured stages and candidates that function as a separate business unit. Conversely, "job titles" do not fit best in a custom object because they are simple, one-to-one attributes of an individual that are more efficiently stored as a standard property on the Contact object.
