they are using a highly optimized A* algo for rout finding

Well, I think its not that the algorithm be written with all Google maps
features in place. Rather it is a open ended question, where interviewer is
trying to find
the candidates view of algorithm design.
@Deepak: It should be fine even if some reasonably good algo is given.

my 2 cents:
For the shortest route finding feature:
I would say: Create a graph with nodes as stations and graphs as the
roads/paths between station. Now Dijkstra's algo can be used to find the
shortest path
