Bloomberg Intern interview questions

The interview process took way longer than I expected. This is mainly due to the unavailability of an interviewer and they canceled my phone interview twice. I finally took the phone interview about three weeks later from I got the interview offer. The interview itself was fine. They asked me basic questions such as what was the biggest challenge or what do you think your biggest weakness/strength was. I was just pissed by the fact that they were not even trying to find another person to interview me but they just made me wait for a long time.
