The allegations of widespread execution problems led to a review and a rolling program of sweeping changes, leaving the junior doctors in the system unsure of where they stood for long periods. The review stated that everyone should be entitled to keep any previous interviews in hand and also have an interview for their first choice if this was in England, with Wales and Scotland deciding to interview all applicants for all posts. Applicants for English programmes were able to make any of their four initial choices into their new first choice if they wished, in order to maximise the number of interviews they would have. This extra round of interviews was called Round 1B. Estimates are that there were 30,000 extra interviews requiring at least 15,000 consultant hours of interview time.
