Crowe LLP Internship interview questions

I was contacted without applying for the internship position based on my resume I had posted. There were two back to back interviews at my college campus. My first interviewer said that they had placed me in the wrong position and matched me up with a different interviewer for the second round. Both interviews were standard personality questions and a few questions asking us to define terms related to the position. I was invited to the second round of interviews and an office visit a month later. They treated us well, took us out for nice dinners and put us up in a hotel. However, I was still matched with the incorrect position. As a result I was interviewed by two additional people in the wrong department. They then announced that they would let us know if we got it next week, but no later than two weeks. 15 business days passed and I still had not heard from the HR. I emailed the representative who had told us she would call within 2 weeks, but she never responded. The fourth week after the last interview I received a generic email from firm-wide recruiting saying I had been denied. Luckily, I gave up on this company after my emails went ignored and had already accepted another offer. I am truly surprised that a firm that spent so much time differentiating themselves based on how they treat their employees, in addition to the time and money treating the potential hires really well, would handle rejecting an employee by ignoring them and sending them the results of the interview two weeks after they had promised. I surely hope that my case, between placing me with the wrong interviewers and not responding to emails, was just an unfortunate fluke in the hiring process.
