All I can say about myself is that I was a student at DPIR. What they care about is your excellent grades and research proposal. What is secondary is your letters of recommendation.
[start]They don’t care about applcants’ work experience unless they publish in Q1. Even if they have publications in Q1, the committee will not value them unless applicants meet minimum requirements anyway. If you apply to the US schools, they will consider the entirety of your profile. However, in the UK, especially IR departments, they prioritise academic excellence (excellent grades and proposal). Other attributes are just added values which will only be valuable to your application when you meet or go beyond minimum requirements.[/start]
[start]With regard to having been approved by a potential supervisor, this matters significantly in other IR departments in the UK but not in Oxford, Cambridge, and the LSE. This is because the PhD committee is more powerful and authoritative than potential supervisors. There are many instances that potential supervisors want this and that candidate but are declined by the committee.[/start]
