Bro at least you have some responses.. I sent almost 100 resumes and got 0 reply atm 

I think the process normally will be .. you got the offer letter. signed it return to new company -> tender yr resignation -> subsequently your company will apply for permits. normally permits will be approved.

mine case which happened recently.

was given verbally and email that I have got the offer from HR A-> i proceed to tender -> HR B gave me a hard copy of offer letter to be signed and return-> HR B apply permits -> Permits got approved after 3 business working days -> HR B ask me to tender, but i told HR i already tender -> HR B ask me to come to singapore for medical to complete the process.

HR A and HR B are two different person.

Your EP validity period is..?

400? single room?

How come everyone's room seem to be less than 1000. Mine is 1000 in pasir ris.

I think the chances to find a single private room for 400 is even lower than the chances of hitting the lottery.
Unless you share room or you know the owner very well, that price is somewhat impossible in my opinion.
The best I could find also is about 500 without AC.
Why so low? With your EP Pass, your pay should be able to easily cover 600-700 rental.

$400 is more like rental in JB
