[07] PREP TIPS
[08] PRACTICE
Use the requirements below to choose relevant examples from your work. For each example, explain the problem, your contribution and the result. Ask your recruiter which skills the interview will cover.
Prepare an example of a kernel or compute bottleneck you measured and improved, and practice explaining the profiling approach you used.
SF Tensor's work centers on making GPU compilers find the fastest kernel forms, which makes performance tuning a core skill.
Source postingOutline how you would verify correctness of an optimized program after a series of transforms.
The company proves correctness at the end of its compiler pipeline instead of at every transform, so verification strategy is central to the work.
Source postingThe current posting asks for:
A PhD in Math is strongly recommended but not required: what matters is what you've proven and built
Someone with good judgement about when a full proof is worth it and when a cheaper guarantee is enough
Someone who's pragmatic about tooling and knows when SMT works, when an interactive proof is necessary and when custom decision procedures are necessary
