I have thought of that possibility, but find two things strange about it.

1. Half a dozen companies being dishonest in exactly the same way is tough to believe. It's too much coincidence. I don't see a reason for dishonesty in that area. Technically insufficient solutions should be easy to explain as a rejection reason.

2. Having attended the interviews in question, I rarely choked on that kind of question and earned plenty of praise from interviewers with little assistance. I'm not long out of school and typically have a knack for those kinds of problems. While I can't see how strict the standards are and what the other candidates are like, I'm not seeing the negative feedback that indicates improvement needed.
