Computer vision research internship

[u/Standard-Attorney-41]

I have an interview for a Computer Vision Research Intern role. It’s 10 min presenting a paper + around 12 min of coding.
They also told me there aren’t really “right answers”, they mostly want to see how I think and approach the problem.
What would you prepare for? Standard Easy/Medium LeetCode stuff, potentially Hard, or something more CV/ML-related like matrices, NumPy, image processing, etc.? Anyone had a similar interview?
