TBH their offer seems a bit low, especially considering your experience and the hassle of moving. You should definitely counteroffer, highlighting your skills and the costs involved. Also, talk about your long-term goals and how DE Shaw can help you grow. If they're not flexible, don't be afraid to look elsewhere. You've got some leverage right now, so use it! Hope that helps :)

Have you tried asking them directly why they've offered this specific package?

Given your 10 years of experience and strong skill set, do you think it's worth negotiating for a higher base salary and relocation assistance, or should you consider the offer if DE Shaw remains firm on their terms?

Staying at a redundant role is too high a risk. It can cost you both financially and growth wise. I see that you have not mentioned anything about the role at the new company. If I were in the spot, I would take the new offer if a. Bangalore is not my home town AND b. The new job seems interesting to me. 30% hike is decent any day

In the current market, it's seems to be a reasonable offer. In addition, the new job gives you the opportunity to stay relevant. my 2 cents.

Try negotiating further.. if they don't agree to increase the amount, accept the offer but keep looking for somewhere else. Once you get an offer which meets your expectations, deny DE Shaw from joining clearly stating that you're unsatisfied with the offered amount and getting a better offer elsewhere. This will definitely make them realise that they're low balling you and if they genuinely want you to join then they might match the compensation.
