You have the ability to start and stop a One-Way Interview if you are in a time crunch.
For example, you can answer questions 1-3 today and 4-10 tomorrow.
Just be sure to submit everything before the given deadline.
When you log back in to Spark Hire to complete your interview, simply proceed to your interview as if you were starting it over again.
The interview will show you an updated number of remaining questions and you will follow the normal steps to complete the One-Way Interview via webcam.
