The lesson for any potential employee is to stay far away from any company funded by SoftBank.

The inflated value may help the CEO get a big payout (like WeWork) or help the company raise lots of capital (like Uber & Paytm).

However, you are probably joining a company with an unrealistic valuation like Uber, WeWork, Wag or Paytm. If you have options, you will always be underwater. If you have RSUs, they may never appreciate.
