Which recruitment website has the best effect?

At present, there are three major petroleum websites in China, namely China Petroleum Talent Network and Petroleum Talent Network. From the effect, China Petroleum Talent Network and Anywhere Petroleum Talent Network are dominant. The original petroleum talent network has been established for the longest time, but the effect is very poor in recent two years. There are not many resumes. The service of China Petroleum Talent Network is very professional, and the upstream of petroleum is the best. Anywhere petroleum talent network may be more prominent in petrochemical industry, but the upstream has little effect.
