After the good news,
1) You wait for authorisation to hire you. (6 weeks)
2) They make the offer and send the contract (2 weeks to sign and return)
3) You sign, scan and return the contract, with indication of 1st available date
4) They reply to say thank you and give planned start date. (1hour later). Also
the pre arrival documentation you must prepare and FAQ's
5) Hand in your notice and prepare for departure.
note: these were roughly my times. It does seem a bit complicated, but I'm sure it's worth it to get in.
