APM Terminals Accounts Payable Assistant interview questions

After applying online, they called after about 3 days to schedule for the aptitude test and personality test. After the test they called ,within an hour, to schedule for the next set of aptitude tests which are more or less similar to the first ones. I then went for the 1:1 interview with the HR and the Senior accountant. I received a call after about 1-2 hours saying they had found an internal member of staff to fill the position which made me wonder if the whole process had been a sham. the interview was mainly situational based.
