Hello friends, sharing my timeline here as I just got news last week that my application was finally successful.
I'm from the Jan/Feb 2021 batch of applicants. It's been a really long wait but all in all, my advice is that it helps to email them a bit to follow up, esp. if you're already done with your medical, though I think the recruitment unit is pretty swamped at the moment themselves and could take some time to reply (but I realised from my experience that eventually, they will do so). Hope my info could be useful to you:
Pre-Interview
20 Feb (Sat): Email received for shortlisted interview
9 Mar (Tue): Call received to attend interview
11 Mar (Thur): Email received with interview details
17 Mar (Wed): Interview day
Post-Interview
24 Mar (Wed): Received call from MOE asking if I'm ok to change my CS1
30 Mar (Tue): Received call to clarify on internship experience
9 Apr (Fri): Application status on portal changed to 'Shortlisted'
26 Apr (Mon): Email clarification from HR saying application still processing and possible offer by 8 Jun and AOD is estimated to be July.
27 May (Thur): Email + SMS received to go medical
8 June (Tue): Medical at Raffles Hosp. On the same day, MOE emailed to say AOD has been delayed to 20 Dec if successful.
<radio silence for next few months - I sent some emails in between to ask for updates. HR mostly replied to say that it is still processing>
Fast forward to early Sep:
HR got back to share that they need to do reference check with ex-employer.
After another ~2 weeks:
Received email that I've been found suitable for the position and will receive offer package soon (I'm currently waiting). I'm told that my AOD will be 20 Dec 2021.
Press on folks and wishing all of you the best of luck!
Hope that our paths will cross one day!
