Right now yes many banks are in hiring mood like Barcleys, Merill Lynch, Citibank etc beside many electronic companies like Motorola etc. Not sure about Credit-Suisse, as I have heard from friends that they have opened a development center in Pune with Wipro and most of the projects are shifting there.
Anyway if you are single or/and ready to share acco with other friends then salary anything >SG $4200 will be fine. But if you like to stay in independent apartment and have a modest/comfortable living then it should be >SG $5000. Rent is increasing in leaps and bound in Singapore, so be ready to shell out SG $1200 for any modest apartment. For searching job, I normally look into sg.jobstreet.com, jobsdb.com and our good old tech.groups.yahoo.com/group/ezlink/messages .
If you get job through some vendor then bargain hard and don�t forget to include medical insurance in your CTC.
If you wish to come here and search for job, govt have some kind of visa by which you can stay here and search job for 1 year.
Hope this will help you.
