Based off of your posting on another website: http://www.careercup.com/question?id=5114718433837056
I gathered the name of the company is Micron. A quick look at wikipedia shows Micron was founded in Boise, Idaho: https://en.wikipedia.org/wiki/Micron_Technology
I also noticed they work with "many forms of semiconductor devices, including dynamic random-access memory, flash memory, and solid-state drives." - Hence the first hint towards a "place where ohms law is checked every day".
I also found that if you remove the "B" from the from the front of "Boise" - you get "Oise" - an area of France that according to Google has many winerys and wine tasting tours. A nod towards "you can feel the grapes (without the first letter)."
On the clue you gave - I think the (Golden State) in parenthesis is your inclusion since you say you have guessed California so far. However I can't really find a direct connection to Boise and gold except that some gold medalists come from Boise in different sports and that Idaho in general seems to be popular for gold panning. There is also a city in Idaho named Golden - how that relates to Boise I am not sure.
Probably a stretch but it was my lunch break and I wanted to give it a shot. I really do hope you will be honest with the interviewer if you get an answer from the internet rather than passing it off as your own since it appears you are asking on multiple sites. A lot of times these questions are more to see how you think rather than if you get the right answer. In fact it could even be a nonsensical riddle just to see what you come up with.
