Boston Consulting Group Client Services Assistant interview questions

The interview process was pretty extensive with lots of rounds. First round included a basic behavioral interview with HR over the phone. Second round included three 30-minute behavioral interviews over Skype. Third round included two in-depth interviews in person. Everything went well but they never got back to me regarding whether or not I had gotten the role. I clearly did not get it, but it was left up to me to figure that out. Emails, calls, and voice messages will not be answered if you do not get the role. I liked the people I spoke to but the company is clearly unprofessional and insensitive to prospective candidates. The process wasted weeks of my time during my final semester of undergrad.
