They spent most of the time asking technical questions about NAND flash and semiconductor physics. The semiconductor physics part may be the hardest part. They asked how they worked. What's the benefits of NAND flash versus hard drives, what kind of problems might occur in NAND flash that we may encounter. They also asked if I've ever worked with a group. At the end they mentioned they wanted someone for 6 months (summer and fall) but I wasn't able to do that.
