If you have applied for a job, you can withdraw your application at any time as long as you have not received a booking confirmation (thus haven't confirmed a booking request).
However, we recommend that you only apply for jobs if you really want to attend those and are available. If we notice you thoughtlessly sending in applications, withdrawing them shortly after, we will know that we cannot rely on them.
Of course, there's always a possibility for something unexpected to come up, which is why you might be no longer available. That's what this feature is for! :)
