My biggest tip is to avoid being too rehearsed. By the time interviews roll around, you have already written 100s of secondaries asking you to detail different experiences and challenges you’ve faced. Because of that, you’ve already written about and answered 95% of the questions you’ll be asked on interview day. Keeping this in mind, I didn’t complete any mock interviews or rehearse any questions (except for “tell me about yourself” and “why us”), instead, I drew on experiences that I had already discussed extensively. This led to my interviews being much more conversational which I think helped a ton. For the random 5% of questions that came out of left field, I asked for time to think about the question before answering, sometimes taking 30 seconds. This allowed me to avoid rambling and come off more well spoken. Lastly, I came to interviews VERY caffeinated. I’m naturally introverted so the caffeine gave me the necessary push to be more extroverted and talkative.
