It's all about where you place the key light, how much fill you use (in this case none or almost none) and how you light the background. Try moving the key light (your main light) around until you get this look. Then decide on how hard or soft you want it to be (add diffusion to make the shadows softer -- in this interview the nose shadow is fairly soft) and then treat the background. In addition, we usually add a small amount of backlight, though here I think there is none. Not needed as the background is rather hot.
