1st part of the process was an in-person assessment centre. You won't get reimbursed as they do not reply to any emails.
2nd part of the process is an online interview which is where "the interview will take place with a panel of two Amentum employees and will last approximately 45 minutes. The interviewers will as more questions to find out more about you as a person, including your studies, extra-curricular interests and why you have applied for a graduate role with Amentum". HOWEVER, they will sheg you over as most of the questions were technical and job-specific questions so be prepared as they will not warn you.
They won't even give you feedback as once again, they don't reply to any of their emails
