Interview: Writing & Analytical tests

Folks, I was informed that they require me to take a Writing and Analytical test along with 7 interviews during my onsite interview. I am preparing for the usual finance material that should help in the interviews but I am not sure of what to expect in the tests. Did anybody else experience this ? Any ideas on what to prepare for ? thanks

I think the writing and analytical test is the one that goes with GRE or Gmat tests.
