I went through a GPU compiler loop last year. For me it was two technical screens then an onsite with a few deep dives, but it varied by team. I barely saw LeetCode style questions. Most coding was C or C++ plus compiler flavored graphs and systems thinking. What helped was building a tiny LLVM pass and being ready to explain CFGs, dominators, SSA, and a simple register allocation via graph coloring. I also drilled topo sort and parsing a small IR while talking out loud. I used timed mocks with Beyz coding assistant alongside prompts from the IQB interview question bank. Keep behavioral answers to about 90 seconds using STAR. You got this.

"The interview went well; the staff were friendly and professional. The hiring process begins with a phone screening, followed by an in-person interview. The interview itself took approximately one hour and involved a series of questions from multiple team members."
