2k starting pay for executive even for local bank like DBS is a joke. You are getting short changed big time. Most MNCs are offering at least 3.4k for an executive.

For the 3 local banks, fresh grads will either go in on the MA track at 4.8-5.2k or normal track at 3.4-3.8k. Either you really CMI or they are offering you a diploma job.
