Arundhati made her debut in a Tamil movie Veluthu Kattu (2010) which was produced by S. A. Chandrasekhar.
[citation needed] Director and producer S. A. Chandrashekar spotted and approached Arundhati, then still a student, in a temple and offered her a pivotal role in the film Veluthu Kattu.
[citation needed] S. A. Chandrashekar gave her the screen name Arundhati, which was then adopted by the Tamil film industry.
She was very choosy about her role, and this resulted in her turning down some offers until she acted in Bodinayakkanur Ganesan (2011) and Sundaattam (2013) opposite Irfan.
In 2014, she appeared in a challenging role in Netru Indru as a police officer who is disguised as a prostitute.
