Got a contract job at TCS. Should I take it?

Hi! I have 4yrs of SE experience. I finished masters last December in CS. I have been applying through a consultancy to companies. Recently, I have got contract job at TCS through that consultancy. I am on OPT visa. I am not sure if I should take it? Given the current market scenario, what do you recommend? I also don’t have other on-going interviews for full time or contract role.
