MPC Runner interview questions

I was contacted by phone, a day after I applied on line, by very enthusiastic HR employee, answered a few basic questions,like where did you hear about us, what is your availability, do you know how to work in Excel and office setting. Said they would call back to confirm in person interview date, but never did.

Applied online, through their jobs portal and didn't hear back for about 4 weeks, I then received an email asking further questions which I responded to but never heard back from them.
