Generally if a person's IQ differs from yours in 12-15 point increments, you can get a general sense that you are smarter than them or they are smarter than you from a long conversation. Someone with an IQ 30 points or more below yours may require you to 'dumb down' your speech in order for them to understand your points; while someone more than 30 points of IQ over yours may have to simplify the way they express themselves in order for you to follow what they're saying. Smaller differences are very difficult to detect without testing. A psychologist with some focus in IQ testing may be able to estimate within 10 points from a conversation.
Caveat: this assumes all speakers have the same native language.
Yes, IQ is what IQ tests measure, but someone with a 70 IQ still has challenging intellectual limitations that will limit what careers are possible and someone with an IQ of 130 is noticeably better than average at learning and reasoning.
