Several rounds. First round was test second round was telephone interview. Got through to the final assessment day round with group project and interview. Did not make it in the end

Pretty standard graduate hiring process. I have no issues with this. The issues come with the lack of professionalism from the company. I did not hear anything about my application for three months. After two months, I sent an email requesting an update on my application and received no reply. I understand that there are many applicants for grad roles and it takes time to consider all applicants but to not even send a simple email updating me on my application is completely unprofessional.
