Interview after one-day review of secondary?

Hi everyone,

I applied very late and am still being invited for interviews. I sent in my secondary to Einstein via overnight express on Monday, they got it Tuesday morning, and I received an interview invitation on Wednesday afternoon! Is this normal? Is Einstein just incredibly efficient, or should I allow myself to think that they might have really liked my app? Either way I'm psyched! Makes me really want to go there.

Thanks for any comments you might have.....
