What is the effect of resume optimization service? Is it worth it?

I just used this recruitment resume optimization last month. Let me talk about my feelings: on the whole, I am satisfied. I just bought this service this morning and a consultant contacted me at noon. Our telephone conversation lasted about 1 hour, and the consultant probably asked some questions around my target position. Easier to communicate. I bought it elsewhere before, but it was difficult to communicate. You can give me a message in a few hours. The consultant hired is still professional and responsible, and the resume is really different after the change. If you want to talk about the effect, I have voted for 30 companies before, and I have accepted 2 or 3 interviews. After I used it, the average number was about 7-8 per day.
