For some students, like me, the interview was their favorite part of the application process while for others it is literally a nightmare that they dread for months. I hope that the tips I offer below will be a foundation for your interview preparation.
Each school has a different way in which they conduct their interviews and it also varies based upon who at that particular school interviews you. The best thing you can do is to read any material that the school has regarding their interview process. Another good source is to ask any students you know that may have applied to that school or who attend the school what they thought of the process.
In my experience the faculty/staff/students who were doing the interviews genuinely tried to make it a relaxing experience and more of a simple conversation than a line of strict questioning. This made it much more relaxing, but I did do some preparation beforehand to try to get a handle on what types of questions would be asked.
A good rule to follow when preparing is that if you write about it, be prepared to talk about it. That means if you put on your application that you were a surgical assistant for 5 years, you need to be prepared to talk about surgery, instruments, procedures, etc.
A second good rule to follow is to educate yourself about the profession and current events/challenges that may impact it. For example, if there is new legislation nationally or within the state that you are interviewing in, you need to take the time to read about it and figure out how it will impact the profession. Another common topic is new/troublesome zoonotic diseases that would affect veterinarians as well as their patients and clients.
The third and final rule would be to practice interviewing! Many colleges have a career center or some office within the college that has people who will help you prepare for an interview and even practice with you. Sometimes it helps to have someone there practicing asking you questions to tell you if you use your hands too much when you talk or are bouncing up and down because you are nervous. You can also ask a friend or even a veterinarian to sit down with you and help you practice.
I genuinely enjoyed the interview process and in my case, it just felt like it was a conversation and the chance to meet new people. I wish everyone good luck and hope that they find the experience equally enjoyable.
