The 98 problems are tagged with the firms that ask them and ranked from easy to hard so you can drill the patterns in the order interviewers actually use. Data Manipulation crosses the boundary between the math, coding, and markets sections of a typical quant round, so candidates pulling from a single track usually still encounter it.
