Boston Consulting Group Executive Assistant interview questions

Completed two phone interviews and two office interviews which also included a web interview with two employees at a different office location. After completing the interviews they called my references and left voicemails for three people. Each of my references called back (multiple times) and their calls went unanswered. After another month of waiting, and them making excuses for the decision wait time, they called and informed me they were not proceeding with my application. The entire process lasted almost two months. I felt it was incredibly unprofessional to contact my references only to blow them off and then string me along for another few weeks.
