Interview Check

I am interviewing my uncle because he is an electronic engineer and owns his own company. He is successful at what he is doing and I think he would be the perfect canidate to interview. In addition to the other questions I willl be asking him, I will ask him about what kind of struggles he had to go through to be where he is at today.I will also be asking him what he plans to do in the future with his company and ask about what kind of different equipment he makes.
