I think that sounds more like an INFP who thinks they're an INFJ. The majority of infjs I've spoken with don't mention that at all. maybe its because I'm an infj too ? but well that OR is not something I think you will encounter with someone who is an infj as well

I also found that very few INFJ's do their part in carrying a conversation or maintaining contact, even though this is a common complaint they have in others as such, I think the time between two infjs will likely hold long moments of silence with the occasional avalanche of highly interesting questions, which will likely come predominantly from the more assertive infj of the two. but that's just conjecture on my part based on the majority of my experiences on talking with other infjs
