Currently work in data is still relatively limited. But, India is in the process of overhauling its data privacy regime. And a new law - the Personal Data Protection Bill - is in discussion for a long time. Once that happens (likely, soon) there will be a lot of work in this space, much like after introduction of GDPR in the EU, data work has increased significantly. You can prepare for this, of course. Read up the discussions that have happened around various iterations to the PDP Bill to get good context to the law. Most important being the Srikrishna Committee Report. Then read up the Puttaswamy judgment that held privacy to be a fundamental right. There are several important foreign judgments such as Shrems. Read up the GDPR of course. You will good material on the law on gdpr.eu. Read how the GDPR compares with the Indian approach to data protection at https://www.ikigailaw.com/comparative-analysis-general-data-protection-regulation-2016-and-the-personal-data-protection-bill-2019/ . The Ikigai  Law and Nishith Desai blogs generally have a lot of material on data privacy. Great stuff on iapp.org as well.
