2007
The Unwritten Rules of Interviewing. SIAM Student Chapter Seminar, Rice University, January 12, 2007, Houston, Texas. This is an earlier version of the talk that I later gave in June, 2007 at the AGEP seminar, but without the discussion and extra materials included. Hence this points to the latter and much improved talk.
