Is the salary adjustment for 4,000 back strict?

It should be a special industry and management position or a core position. Most people quit their jobs in order to raise their wages, so many people have had the experience of falsely reporting their wages. Similarly, HR has seen this situation a lot, so before the final Offer, it will make a callback to the actual salary of your last company. The way of callback is nothing more than providing salary flow, salary certificate, salary slip, mobile APP salary screenshot, salary receipt SMS and so on. This is actually the same key information that you need to tell when you entrust a lawyer to help you with a lawsuit.
