发帖数: 1567 | 1 第一轮电面完了多久有消息啊？google貌似真的很慢。
BTW，拿到offer的同学你们都什么时候开始？ 如果intern 5月初开始的话，我要考虑要不要再等下去了。
贡献面试题：
1. research
2. given two sets, find the different elements
3. Suppose that you write something to a disk, then read it after a while.
And the data is corrupted. Now, give ideas to identify where the problems come from in the mem hierarchy.
4. What happens when system call happens? E.g., you call a system call
write(void *pt), how to pass data to kernel since kernel has its own
virtual addr space?

虑要不要再等下去了。
这个是先排序然后binary search么？
problems come from in the mem hierarchy.
any idea for 3 and 4?

发帖数: 226 | 3 3: write a toy program to write different size data and then read back and
verify.
the system should perform real write to main memory on cache misses, and to
disk when disk cache is full.
so based on the size when data appear to be corrupted, we can tell whether
it is cache/dram/disk problems.
4. please refer to | r**u
