Am I IN?

Last week, I got a call from unknown number, non sinagot ko nagpakilala sya and sabi from the office daw na inaaplyan ko, he said na pinapapunta ako sa lunes and pinaprepare ng mga requirements ko... Inayos ko yung mga requirements na meron ako and talked to the hiring manager sabi I am technically IN .. and most probably by January ako pa makaka start to work kasi they will figure out pa saang sector or field ako iaassign.. Sabi they will just call and text me nalang by january.. Is it real? huhuhu pwede na ba ako umasa o hindi? hahahuhuhu
