A while ago I had a conversation with a colleague of mine, and we’re talking about an applicant who applied for a position that he does not have any background knowledge of, no experience with the said field and completely unaware of what he is getting himself into.
He had not even done any research beforehand and so did not understand even the name of the position. I said that he was “point blank” with my colleague and we continued our discussion: none of us noticed I had used the wrong idiom/phrase.
Later tonight, I felt that something was wrong and remembered the phrase I used wrongly, so I tried to think of that specific phrase that I meant to say but had failed to do so correctly. It’s supposed to mean something like “going into a gunfight empty-handed” or “taking an exam without studying”.
Google not seem to help, and I don’t know any native English speakers in real life.
I posted this on reddit, and got some really close answers like “Jumping in the deep end” or “Going in blind” which are close to what I was meaning to say cause it supposed to sound like going to recklessly commit yourself into something while being ignorant of the things you’re about to encounter, or something like that.
But it still doesn’t sound right; can you help me find the phrase I’m looking for?
