How long does it take to get a job offer in Hong Kong?

Hello I am planning to shift to HongKong next year on quality migrant visa from India. I have two ueries: 1. How much time does it usually take to get job after moving to HongKong. 2. I noticed the International / English school have long waiting list. Will there be waiting list for admission in these school for grade 11 as well? Thanks VV
