Best city to live in India for a SPM / PM (product roles)

If you are single than Banglore over Pune and Hyderabad.
With family Hyderabad and Pune are much better.

Best on what metrics?

Career, Bangalore >>>> anything else for any tech/tech affiliated role.

Other factors, depends entirely where you are from, your cultural fit etc.

Dehradun

Bangalore is still the best when it comes to opportunities. But I feel Pune is better from quality of life standpoint

How come people voted for hyderabad? Explain as after this new flyover opened,I am feeling like I am in Bangalore without being in Bangalore.
