First of all, it depends on what interview you attend. If it is an interview in an ordinary company, you can say.

I found myself interested in music since I was a child, and after some training, I found that I have some talents. If a person has the opportunity to study his favorite major, it is very lucky. For this love, he chose this major.

If he participated in music performances or interviews with stage performers,

I watched TV since I was a child, and saw the singers standing on the stage singing loudly. I was attracted by such performances, and I was exposed to vocal performances from then on. Vocal performance is not everything to me, but it belongs to my favorite industry.

I hope to adopt it, and several years of interview experience is absolutely effective.
