Hi Séverine. Apologies for a slow response -- I don't always see the notifications!
Anyway, I suppose it depends on your exact use case but I pretty much always recommend using "T ouchpoint.Session.FormPage" in these scenarios because that ensure it will suppress the touchpoint ONLY if they are on that particular page when they submit a form (like a job application form).
If you used "Touchpoint.Session.ReferrerPage" I think it could have unintended results. For example, what if the career page was somehow their referrer but they then navigated to & filled out a form where you DO want a touchpoint, like an ebook download... in this scenario, the touchpoint would be suppressed due to its referrer if you built the rule this way. I don't think that's what you'd want so I'd recommend not trying to do it this way, just stick with Touchpoint.Session.FormPage!
Hope this helps
