Due to COVID-19 all my interviews were done online. Through an employee referral, I went through three rounds of interviews. First one was 30 minutes, very casual and not technical. Explained my research interests and background. Second one was 1 hour, more technical. Again explained my interests and background, had some technical questions related to my work to test my competency in optimizing software. Third round consisted of three back to back 1 hour long interviews followed by a 1 hour meeting with the manager. Much deeper dive into my background on HPC, scientific application, and programming. Equal mix of technical and behavioral questions.
