Table 4: International Candidates during the 2022 UMF Cluj International Admission. Figure 11: The distribution of the candidates based on their continent of origin. In the analyzed 18 days in which _[PERSON]_ worked at UMF alongside human operators, the chatbot received a total of 5982 messages from candidates with a total of 16,459 responses out of which 15,843 (96.3%) were from _[PERSON]_, as such it can be argued that _Ana_ implementation proved successful in providing a 24/7 online admission support and assuring that the most basic and repetitive questions are addressed by the chatbot, and not by admission staff at UMF Cluj, which received only 809 messages from candidates (13.52%), representing the more complex questions that _Ana_ couldn't yet provide answers (See Table 3). As depicted in Figures 12 and 13 we can see that with the exception of Wednesday, responses from human operators to candidates inquires are less then 1, meaning that a large number of questions addressed by candidates to operators are not answered in the day they are addressed. This is due to the fact that UMF Cluj, like most universities, has only a Monday-Friday, 8 working hours schedule for answering questions through its admission staff, moreover as most candidates from the 2022 international admission were on different time zones than Eastern European Summer Time (EEST), there are also cases in which time zones between Romania and the candidates country are very different and thus provides a challenge for personal communication between international university candidates and the local admission staff.
