For my case:
23 March 2013 (Friday 3:00pm)====================
SI @ KLCC for Project Planner/Scheduler .
Result : KIV for different post.
5 April 2013 (Friday)==============
Contacted(phone) by the Petronas, being offered different post (contract basis, not direct hire). They asked me if its able for me to join them on 16 May 2013. Since I hv to gv 1month-resignation-tender, so I politely discuss with them about any possibilities to register on 1st of June (it will be 2nd June @ Kerteh, working Sunday).
16 April 2013 (Tuesday)================
Contacted(phone) by Petronas HR asking my current employment`s payslip. I emailed them immediately, and HR replied my email at 4:50pm written "Tq".
22 April 2013 (Monday)===============
I called them asking the status, since Im waiting for their Offer Letter to be attached with the resignation letter and I need 1month-resignation-tender to be submitted on 30th April, next Tuesday. 1st May (Wed) will be the starting date of my resignation period. Petronas`s HR ("Ms.A") told me that the HR management will manage the offering prosess (salary/date of registration etc) as soon as possible probably this week and will contact me by phone.
Still patiently waiting for the official offer letter. Oh and before that, HR do mentioned about maybe somebody from her office will call me to discuss about salary.
Patiently waiting. It just 1 month since the SI session but it feels like AGES

err, you don't have to do any medical check up before they give you the offer letter?
