Ex Zomato, here. Adding my review:
Pros:
• Some truly good people. Thankfully got a lot of business insights as an engineer too.
• Pay was good.
• Chance to make a significant impact on a widely-used product. Felt that everyday, personally.
Cons:
• Working hours are messed up, super high pressure too
• Senior leaders are not very empathetic, they will almost taunt you for not turning up to office or taking leaves
• Growth in salary became quite less by the time I left. Poor stock allotment too.
If you don't mind work stress, Zomato can be rewarding.
