Walmart would usually lowball you if your current CTC is less or you don't have a competitive offer in hand. So please negotiate with HRs and don't give up. Walmart is very strict regarding their hybrid work policy so you'll have to work from office atleast 2 days per week. Even if you're going to your hometown they usually won't give WFH and you'll have to take paid leaves.
