Resume optimization, an irregular service, is actually difficult to adjust. I have used resume optimization for recruitment, and I have also used similar resume optimization services on other platforms. You want to say contrast? Each has his own merits. The advantage of hunting is that it is professional enough. The general consultants are HR of some big factories or head companies. However, the shortcomings are also obvious. Compared with some simple ten-odd resume modifications, the price of hunting employment is relatively high. Choose according to your own budget and situation. If you want professional advice, you can choose to hire. If it's just a simple tinkering, then the rest will do.
