Can i join ca articleship after 5 years of passing ipcc?

I want to work for 5 years after passing IPCC and then join articleship. Is it possible? Also, I'm 21 years old now so if I take this 5 years gap, by the time I pass CA Final I will be around 29. Will a get a job at that age? I don't want to do private practice so I must have a job. Please help.
