Career Decision Advice – Wipro B2 Band vs External Offer

I’ve completed 90 days on bench at Wipro (B2 band) and was just allocated to a billable client project. However, the very next day, I received an external offer from another IT firm with a CTC of ₹22 LPA—almost double my current package of ₹11.5 LPA. Given this timing, I’m unsure how to proceed. Should I accept the external offer or continue with the new project at Wipro? What are the risks or considerations—especially regarding notice period, bench history, and long-term growth?
