The short answer
Look past the headline number to what you actually own and what it might be worth. Ask for the specifics: how many shares (not just a rupee value), what percentage of the fully diluted company that is, the strike price, the current fair market value, the vesting schedule and cliff, and the exercise window if you leave. A big number over a huge share count can be a tiny real stake, and a high strike eats your upside. There is no way to value private equity precisely, so treat it as a lottery ticket with real odds attached, weigh it honestly against cash, and do not take a large pay cut purely on a number nobody can promise.
