So if there's 15 candidates for a job you'll end up with 18 pages on the multipage?

That doesn't sound like a good idea to me.

Also, if each additional page is for an individual candidate why would you duplicate page 3?

Have you considered any other approachs?

For example a form with a combobox/listbox listing the candidates and various textboxes (listboxes?)

The user selects a candidate from the list and the relevant texboxes are filled with the data for the chosen candidate.

The data in the texboxes could be changed if required and there could be other textboxes to enter new data.
