Recently, I was in an interview and I mentioned I used to practice magic. The interviewer asked me if I could perform a trick for him during the interview, but I said I didn't have any props available. He said in my future interviews I should bring, for example, a deck of cards in my pocket just in case the interviewer wants to see me perform a trick. Do you think it's a good idea to bring a deck of cards for future interviews for situations like this?
My main concern is that I haven't practiced the "cooler, more difficult" illusions for a long time now. I can perform simple tricks, but I feel as though they might not be that impressive, and my interviewer might feel a bit disappointed and I could end up hurting myself if I don't execute the trick perfectly (because the tricks that I am confidently capable of performing right now might be too easy to see through, especially if I make even a minor mistake). I have another interview coming up, and because of my current lack of practice, I feel as though it's more appropriate to play it safe, not bring any props, and if magic is mentioned, describe my experiences and possibly a quick explanation of an illusion if the interviewer asks for something like that. What do you think?
