Key Points

A PhD student preparing for applied scientist/research engineer interviews asks for recommendations of websites to practice coding interviews focused on PyTorch and NumPy.
They are currently doing mainly LeetCode and have found several specialized platforms (nexskillai, tensorgym, deep-ml, leetgpu, and the PyTorch portion of NeetCode) but can’t determine which are best.
The post is a request for community guidance and additional suggestions beyond the listed resources.
The underlying goal is targeted interview training for ML-focused coding skills rather than general software engineering practice.

Hello,

I’m at the last year of my PHD and I’m starting to prepare interviews. I’m mainly aiming at applied scientist/research engineer or research scientist role.

For now I’m doing mainly leetcode. I’m looking for websites that can help me train for coding interviews in pytorch/numpy. I did some research and these websites popped up: nexskillai, tensorgym, deep-ml, leetgpu and the torch part of neetcode.

However I couldn’t really decide which of these websites are the best.

I’m open to suggestions in this matter, thanks.
