leo burnett "interview"

i still remember few days ago there is a women from leoburnett call me for an interview. and she say the interview will be around half n hour. but den i got 1 friend go there for interview juz take not more then 5 minute wow.. how come?
today i went for the "interview" of leoburnett. i reach there before 2pm. actually i feel that the environment is quite nice lah. is look like quite relaxe. the light is yellow in color. and there have a place like cafe with table, sofa, snooker, tv, and bar also. and i was waiting at there.
while i was waiting i start to realize why she told me the "interview" will be around half n hour. u all know why??
that is b`coz 25 minute is waiting her to come out!!!! what a terrible thing. is that the habit for ppl in this field?? 25 minute u know!!! haiz.....
den she start by asking me will i able to work early? around the last week of december...
after that juz tell me what will i do if they hire me... and that`s all.... 5 minute juz pass.... is finish already... this call an interview???
i strongly felt that all she ask in this she call an "interview" can actually get through the phone. and i actually dun need to go there to wait for 25 minute also.
and last thing was when will i get to know whether will they hire me for my industry training a not? she ask me to call her next tuesday to get the answer....
haiz.... i hope that the interview next mon at catcha not like this.
