Feedback is extremely valuable. But you should take it with a grain of salt. If you are rejected several times, with feedback, and some of that feedback happens to overlap? Definitely something to consider fixing.
If you want feedback go see a therapist or career coach or talk to friends, family, mentors, previous coworkers etc. Don't expect a hiring manager to do this for you. As someone who has interviewed hundreds it would actually make me resent you because if you can't show the initiative or take the responsibility to improve yourself then I made the right decision not to hire you.
Worst of all I and many others would feel uncomfortable giving personality advice (if that was the issue) and would just lie and give some other reason. It's human nature and would just throw you off course and wouldn't help anyone.
How do they know what to improve if you won't tell them what needs improvement (in your eyes)?
Clearly your strengths lie in organization, communication, and technology, not in carefully interacting with other people (as in Sales, Marketing, Recruiting).
Delegate this to the recruiter so the candidate doesn't get a bad impression of the company they just attempted to join.
