Cisco TAC Engineer Hiring India

Hi Guys,
Recently i got hired for Technical Support Engineer role at Cisco, India (Salary 650,000 INR). Though, from the portal when i applied it showed the role as TAC Engineer and now in offer later it's Technical Support Engineer. Moreover, this is the only job offer i have, and have a gap year of (1.5 years, graduated in 2019 BTech CSE). I plan to do MS-MIS (Management Information System), is it worth it joining this role? Anyone who is working as Technical Support Engineer, can you please elaborate on your daily work.
Is it like customer care? Though my interview was technical with some HR questions.
