Can I stop in the middle of my application and come back later?

Yes. You can start and stop however many times you like in the middle of your application. The employer will not be able to see that you have started and stopped the application, so feel free to act in the way that works best for you.

Your responses are automatically saved when you press "Submit." However, if you'd like to save an answer before you're ready to submit it, you can also like the "Save and Continue Later" link underneath any answer you are submitting. 

When you come back, you will be taken right back to where you left off. You will also be able to edit your responses as long as you have not clicked the "Finish" button at the end of an interview.
