Standard Microsoft interview:

You have 4 interviews scheduled. Three are one hour each, and the lunch interview is an hour and a half.

The interview flow starts with some softball questions, typically about engineering or previous experience. It then typically progresses to coding questions, algorithms, and whiteboard analysis of a system (how to test it).

If you do well, you land a 5th "as appropriate" interview, typically with a higher-level manager.

Start with a random linked list—a linked list with a second node pointer that can point to some random node in the list, or to nothing at all.

Implement a method that will generate a deep copy of the list.
