Multi page Job application

My boss wants me to make a job application page which will require a lot of fields

I’m thinking I will follow the multi page form tutorial to build the pages.

I 'm looking for suggestions on how to best store and send the data since there is plenty of personal information stored in these forms. We have in the past made a fillable pdf and have them email it but that is often problematic due to various issues on the applicants side.

Looking for suggestions
