What Happens After You Apply

Right after you apply, you’ll receive an email invitation from Spark Hire to record your Intro Video. It’s a short, self-recorded video that completes your application and allows hiring managers to get to know you before the interview process begins.

Rather than repeating your background during multiple screening calls, you’ll tell your story once, allowing future interviews to focus on meaningful conversations.

Don’t overthink it—you can record as many takes as you’d like before submitting. Your invitation will come from Spark Hire, so please check both your inbox and spam folder.
