What can we try and deduce from this scenario?
Applicant A: Has the two standard college interviews. Is then asked by another college for two more interviews at their place. Then is further requested for another interview at a different college. Is requested to stay the full span of subject interview period.
Applicant B: Has the two standard interviews. Is then released from the Oxford interviews, at less than halfway through the no. of days required for an applicant for that course to stay for. (Released early)
Both applicant A + B receive an offer from the original college.
