Freshfields Transaction Lawyer interview questions

I applied for the position in Germany. First, there was some misunderstanding as they were using both a hiring company and add in a jobs site by themselves. Then weeks after they invited me on a Skype interview and arranged a date. The iterview was supposed to be with 3 persons and approximately hour long. 15 minutes before the interview their employee called me to rearrange. The second date was after two weeks. Their employee assured me it is not my fault, the interviewers "had work". The interview was with one person who didn`t seem very interested and asked me no more than 2 questions on my CV and experience. 10 days after they sent me an email rejecting me. Overall, I am extremely dissapointed with the experience, as they wasted more than a month of my time as they could have rejected me in the beginning.
