DemandTec interview questions

I received phone call from HR, and went to the office on the following week. The team leader and the PM interviewed me. Some questions about statistics and math, like quiz. Also asked me something about OR, linear programming, etc.

Started with one phone interview, then called for an on-site interview. Interviewed 1:1 with six people, each took 45 minutes. Most questions were about background and experience. Asked to look into one small data set, perform analysis and present during interview. Need to consider and deal with missing data at the first step. Some technical questions are about mixed integer programming.
