The interview was split into two 45 minute parts. The first was a one on one with the COO, which consisted of mostly behavioral questions and details about the company/role. The second was a group call with the CEO, and this one was more technical. I was asked to describe in detail certain components of an API they use (which I also had experience with). I was also asked some general questions about HPC/GPU acceleration, which weren't too difficult (I have some background in this). Expect reasonable technical questions about any sort of expertise you claim to have, as well as a traditional coding style interview question.
