Sample interview questions
I have installed software using Spack and manually built packages with CMake. Challenges include dependency conflicts and version incompatibilities. I resolve these by creating custom build scripts and working with vendors.
I first profile the code to identify bottlenecks, then advise on compiler flags, MPI optimizations, or resource allocation changes. I also collaborate with system admins if hardware tweaks are needed.
I have extensive experience with Slurm, including writing and debugging job scripts, managing partitions, and troubleshooting scheduling issues. I also understand PBS Pro from previous roles.
I assess impact and urgency, communicate with users, and use a ticketing system to track progress. I escalate critical issues to Tier 3 if needed and ensure clear documentation.
I document step-by-step processes with clear roles and responsibilities. I involve stakeholders to ensure accuracy and update documents regularly based on feedback.
