I saw "request a demo" so presumably it's not free and that's a problem. Also Discord works in most browsers so the person they are interviewing doesn't need to download anything
It's free for personal use, I responded to a nearby comment. In-browser is a good feature, I guess Wire can also get there in future, since both, Discord and Wire, are electron-based apps. But I believe call quality is not quite enough to replace Skype, I demand e2e privacy as well.
