What Happens After You Apply

Right after you apply, you’ll receive an email invitation from Spark Hire to record your Intro Video. This short, self-recorded video is the next step that completes your application and can be recorded whenever it’s convenient for you.

Instead of repeating yourself across multiple screening calls, you’ll introduce yourself once, and your video will be shared with the hiring team. This helps the hiring team evaluate your communication style early, making future interviews more meaningful while reducing unnecessary interview rounds.

Don’t overthink it—you can record your video as many times as you’d like before submitting it. Only your final submission will be reviewed.

Please keep an eye on both your inbox and spam folder for your Spark Hire invitation after submitting your application.
