Acquia Associate Engineer interview questions

The management of acquia is incompetent. The process was stingent and lengthy. It was useless. I went through almost 6 round and every round was about same questions. Process was about 2 month and at the end the rejected without sending any mails. Management is worst I ever seen. I didn't understand what is actually want. Literally worst experience ever. They will make you wait for months and will send you back.
