Know it's off topic but no other board will be intelligent enough to answer. Pls help bros

Course: MASt Physics
Secondary academics: A*A*A* A levels, easily top of school
Uni Academics: Birmingham, 87% average in Physics, somewhere near the top don't know for sure
Extracurricular/internships: Some volunteering + 1 very selective research internship

A few days before interview I got in a really violent fight so went awfully, I did tell them this, I'll try describing interview:
2 questions on whether I'd covered Lagrangian and or tensors, hadn't done either
2 academic questions, answered 1 badly 1 "ok"
Question on 3rd year experiment, answered very badly

Was it definitely interview?
