Study path

AWS-style ASIC interview preparation

Practice end-to-end data movement through DMA, queues, memory, interrupts, and firmware. Strong answers make ownership, ordering, capacity, and failure recovery explicit before optimizing throughput.

Tie each design choice to evidence from protocol monitors, counters, reference models, or stress tests. These independent exercises do not describe AWS's official interview process.
