MAnisha,
Banglore is most preferred one now..previously it use to be Mumbai maybe...But i think each and ever city has drawbacks so as Banglore..its poor infrastructure and high cost of living is example..but still people like it ..
I like Bangalore because of two reasons.1.Five years back,the climatic condition was so pleasant.2.You don't feel like staying in a different place. Everybody knows tamil and hindi apart from Kannada. :)
But, due to global warming bangalore has become too hot now a days. :(
I prefer Delhi, which is close to my home town AGRA. Mumbai is the least preferred owing to regionalism and hooliganism of shiva Sena. However, this is only a matter of preference. The foremost significance is job prospects. I am ready to work from any place.
