You have two shortcode who can be used:
[jobsearch_form] or for example [jobsearch_form jobLanguage='ja']
This shortcode have to be use for let the customer have the access to the search form, detail job and then apply, so the customer apply for one job.
JobLanguage is a filter, it show only job who have for example japanese language (it's the field job language on Tamago-db)
[jobsearch_apply] shown only the apply form, it allow the customer to apply without choosing job.
It's possible to put one shortcode on one page and the other one on another page.
