Email capture interstitial when user presses "apply"

I notice some job boards and other types of websites have an interstitial when you press “apply”. It would be great to have the option to either have a popup, or take them to an intermediary page that encourages them to submit their email, with the option to continue without.

This is an example of the feature. Press “book now” in the yellow tab: https://cruisesheet.com/norwegian-breakaway-12-night-miami-to-london-february-07-2025
