The Tata group has not announced any such offer, and the viral link is a hoax.
Tata is one of India's prominent business groups having various businesses under its belt ranging from automobiles to chemicals to power.
A post claiming that the Tata Group, as part of their 150th-anniversary celebration, is conducting an event in which participants would get a chance to win a Nexon car is circulated on social media. The post shares a URL link that navigates to a survey, requesting the users to click it. A quick verification confirms that it is a fake message.
Soon after the message became viral, Tata Group clarified on Twitter that the news was fake and advised the public to refrain from clicking on such suspicious links. Furthermore, the official Tata group's website mentions that it completed 150 years of existence in 2018. The viral message is a scam put out by fraudsters to trick someone into revealing sensitive information. Hence we mark the claim as false.
