Hey Dhruv
I am an applicant myself, I think I can give you a few ideas regarding your
queries.

Go through the library source code thoroughly. Use a code dependency graph
generator to browse code easily. (Easiest way is to run doxygen over the
ublas
directory). That will make going through the code real fast.

Not sure about the format, but the tests should cover as many cases as
possible.

Best wishes
