I got into Lex Fridman's podcast [1] maybe a year ago and was instantly a fan of his depth-first search style. It's often frustrating in other interview style podcasts when something interesting is mentioned but not explored. Lex will often say something like "oh that's interesting, let's talk about that" then that becomes the subject of discussion for 20-30 minutes, but he's good at backing up to the original point after that branch is exhausted. Incidentally he's a computer scientist!
