Thanks for the tips and while the GDPR angle is interesting, but I am not looking to spend more energy on this, they won't be hiring me and I don't want to create some sort of reputation about myself.

As to your question, I am very open about the fact that I don't have the CV experience to show for it, but I am very confident about the technical skills that I do have and in general I come across as confident in the areas I know things about.

The reason I am specifying it here is to give honest context and to show that I'm able to do at least a basic level of introspection. I want to be honest that I didn't go to harvard, MIT, didn't have any prestigious internships and I'm trying to switch industries.

But I am confident that I did ace atleast 3 of the interviews and that last interview, which was the reason given as to why I would not be preceding. This is why I'm seeking some answers here.
