Good start ?!?

Just a few minutes after the I sent the application's mail to a company, I received a call... I was asking for fulfilling some pre-criteria before i am arranged an interview... what a sudden call.. It really surprise me....All happened within less than 15 minutes only...however, this should be a good start for my job hunting...Although it can pay me low salary, but just give a try to attend the interview, perhaps different experience can be gained through that...
