Yup its actually true, Hotel line let you progress very fast. Eg: u start off as Commis 2( 2nd lowest rank) in the kitchen every 6 month u get promoted cause u got degree. until Sous Chef maximum One department chef.
Then if u have the potential u join those big big hotel. u are selected to transfer and become executive chef in newly open hotel or so.

But the turn down point are?
only 1 day off ( never got to happen in Weekend)
Split Shift( employee hate this the most) work start at 9am end at 2pm continue work at 6pm to 10pm.
Holiday, You are Chinese or Malay ,Chinese New year u are entitle to go back home on the 2nd or 4th of the Chinese new year same goes to Raya.
Sometimes, Hotel Busy, call u work 1 week straight without rest.

Well that's about it. Foreign Country has their Union means law or policy protect the staff. but in Malaysia no.

But if u got the passionate to become a Chef, There is no one to stop you. ^^

Good Luck
