&gt; They talk about being polite, wearing a suit, grooming, etc.<p>Yikes, that&#x27;s even worse. Some cultures will actively hold a suit against a candidate. I can&#x27;t say I agree with that, but it&#x27;s a little scary that they&#x27;re giving stock advice to a highly dynamic field, very little of which is relevant. (Polite is good, being relaxed is better. Being suited is good, being comfortable is better.)
