I don't think solution for that is dropping perfectly capable people on the interview. There should be process for clarifying tickets with the team because you don't just drop tickets on developers "out of nowhere" and expect them to ask questions especially if company culture is "drop the ticket on dev let him figure this out". Someone has to either make ticket written in detail so you can drop it on dev without dev needing to ask questions OR make refinement where you get team to ask questions to have input from multiple people because single person is not able to understand all the details of the system.
