Is a panel interview a good sign?

Yes, a panel interview is a good sign. In fact, it's a great sign. A panel interview means your hiring company is interested enough to bring various staff members to the table to learn more about you.

These interviews are often held with executive team members to maximize their time out of the office. However, regardless of who you interview with, a panel interview is a good indicator that your candidacy is going well and you are likely being considered for the role.
