Curves in projective space can be described by either parametric or Cartesian equations. A natural question is how the parametric and Cartesian descriptions of a curve relate to each other. We describe the Maximal Rank Conjecture, formulated originally by Severi in 1915, which prescribes a relationship between the "shape" of the parametric and Cartesian equations --- i.e. which gives the Hilbert function of a general curve of genus g, embedded in P^r via a general linear series of degree d. We then discuss the "interpolation problem" which asks how many general points a curve of given type can pass through (for example a line can pass through two general points but not three). We conclude by sketching how recent results on the interpolation problem can be used to prove the maximal rank conjecture.
