I think in this case, knowing how a GC works was more important than knowing your way around the tools they used. Don't get me wrong, knowing what a compiler does, how to use gdb well, and the semantics of the stack well is important, but I think, in this scenario, understanding the garbage collection algorithm was more important than the tools they used.
