Hmm. when you prove to be more knowledgable than the programmer that was pulled in, to interview you and he starts to go totally defensive and return spiteful responses
( like, what does a rookie like you know? i bet you never had an actual job )
when you calmly asks if any standard like PSR-2 is expected, if there are any preferred frameworks and what version control is used...

well, that went well..
Didn't get that internship..
