I live in a suburb of Los Angeles where every kid in the school district has been issued a chromebook. this is the kind of market share Google will capture. For better or worse.
interview ... any reasonable employer will understand your leaving for a much better income. If they have a bad reaction, you're also better off somewhere else. After you receive a firm offer, be honest with your current employer. They may take the opportunity to counter. "I'm really sorry about the bad timing, but I'd be crazy to turn down an offer like this."
