Emma interview questions

The process was quite long but interesting (I have added 4 different interviews with often the same question over and over again). All managers were really kind and professional. I was very disappointed then when I finally did not get the job because of a reason that does not reflect my personality at all. "we were not sure whether you would adapt to our environment in terms of us lacking hierarchy and structure and being super-fast paced. " while I have discussed this with the general manager and I have very successful experiences with this kind of companies. I feel like HR doesn't really get full feedback from the interviews. I feel like I did 4 interviews for nothing since the result does not reflect the interviews content.
