Rolls-Royce Design Engineer interview questions

After passing initial round interview,i received confirmation on email that my application will proceed to the next stage of recruitment process where I will meet with Hiring Managers that will conduct a more comprehensive review of my skills and qualifications.After one month I received another email where they state that due to a high volume of applications (they changed their mind) they will proceed with other candidates.Two weeks later they repeated the position on job board again.So unprofessional,deceiving and waste of time,I will never apply for this company again.
