I took an online C++ test and would rate it a 7/10 in difficulty. I passed with flying colors, scoring 97%.

One hour later, I received an email stating they wanted me to go through a technical phone interview.

During the phone interview, I did not do well. The interviewer focused mostly on UNIX questions (signals and file system), along with some C-style questions about the stack, heap, and pointers.

I heard no further word until two months later, when I received an email informing me they would not be offering me a job at this point.

How would you implement an STL map on the heap?
