I have received an offer letter from TCS. However, upon researching some articles, I discovered that there is a formality where I need to provide surety with income tax proof or make a Fixed Deposit of 50,000. But, I want to understand what surety entails. I am unable to pay the FD or provide surety as I live with a small family and have a limited income. Will this circumstance lead to the cancellation of my joining? Is there an alternative solution available?
