Oracle v/s Zomato as a fresher

Asking for a friend who'll passout this year. He has full time offer from Zomato, Bangalore and Oracle(currently interning at Oracle). CTC-wise there is not much difference except year end variable performance bonus of 5L in Zomato.

Now, he has decent learning curve in oracle but want to join Zomato to learn more and relatively new tech stack. Issue is Zomato's work culture and job security. Is it worth the risk to take Zomato? (not taking money much in consideration)
