I use simple forms for emails and spreadsheets.
Look at the clone on my github.
Please also read these links for help and forms.
You can directly embed the form on a page or use it as an add-on.
Pulse doesn’t have a database but you can easily connect to one to start that information if needed (it’s PHP based after all)
But as it is without extra programming you’ll be able to:
allow job seekers to upload cv/job application, cover letter etc using the “Upload” Tag. This will get uploaded to a folder in your “Media” page in Pulse
create an online form (embed in your Pulse project) and that data gets emailed to you or also sent to a database - so both ways you can retrieve the info
But you could also Gforms or others as @IvaRo has said and embed them into your Pulse pages.
