Any Valuable Information is Appreciated

Hi I'm a recent engineering graduate and I have got a offer in TCS and I'm located in Gurgaon (TCS GG7). So, I have some questions. 1. Is there any rental rooms available near GG7? If yes then how much would be the rent range? Like 5k is enough? 2. Anyplaces far from GG7 which will have less rentals and not much time taking for traveling to the office? 3. What is the process of searching for rental homes? Like brokers will be there or any apps or I have to search individually once I come there? If Brokers then there would be any scam?? 4. Any Tips & Suggestions that I have to take care of in Gurgaon like what all things are needed in different seasons, how rush the metro and locals would be in the mornings, and I heard it's not safe at night time like lot of gundas will be there etc.. is it true?? Fyi I want to live alone
