since you are only applying for the job at the moment and not reaching the final stages of neg with HR on your pay, I advise you to just go ahead and apply.

I am saying this because by normal application without referrals, there would be many others applying for the same job as you.

If you are a fresh grad, it also depends which uni you are from. But as fresh grad, you can ask for about $3k for this position.

Of course, if you are a local Uni, maybe $3.2k. But if foreign Uni (corresponding uni), $2.8k is also good.

Do you have other relevant experience?

Give this post few more days and you might be hearing more inputs.
