I'm happy to provide more insight, but not sure exactly what you are referring to in asking for a challenge to your thesis but then using my quote as your thesis? I may have missed something, clarify and I'm happy to respond. I find it interesting that you find employers want to provide more feedback. A mere 30 seconds before writing this reply to your comment, I received an email from a client saying "We looked at the resume and don't think he is a fit for our team". That's it. If this manager wanted to help the candidate, he could mention what skills are missing. If the manager felt there was a problem with the resume, he could have mentioned that. If the manager wanted to help me hit the target better next time, he could have mentioned what was missing. I think what you are referring to is feedback after interviews mainly, but this very bland, 'not a fit' feedback is exactly what is most commonly provided to recruiters. If given ample free time, managers will provide more detailed feedback, but that usually isn't the case (particularly in the start-up world). I do have clients that are more willing to write a few sentences, but I can tell you that the norm is 'not a fit'. I don't find managers are in any hurry to help candidates do better next time, which does little to improve the overall ecosystem. If a candidate missed questions on a specific area in programming or a concept, that would be helpful for the candidate to know. I wish more managers wanted to provide more feedback, but for now it is a minority.
