During the interview you should be prepared to explain the technical content of your work as the Interviewers have been asked to particularly explore competences C, though please note that this will not be at the exclusion of the other competences which will also be covered.
Am I right in thinking that it's normally A and B competencies that are focussed on in the PRI, so this is that they have been asked to focus on C competencies based on my application?
The text seems a little inconsistent as "technical content" isn't so much a C thing, is this just a failure of the template?
Given the above, should I try and build my presentation around the parts of my application that I think show C competencies?
P.S. I wasn't expecting to be in lockdown with an 11-month old baby while preparing for PRI - I need all the help I can get focussing on the right thing!
