Why do some companies not go to Inner Mongolia University of Science and Technology to recruit?

Inner Mongolia University of Science and Technology is the university with the highest employment rate among state-owned enterprises in the Inner Mongolia Autonomous Region. More than 50 graduates have entered state-owned enterprises. As for why some companies don't go to the University of Internal Medicine to recruit, maybe it's because the company's hiring direction doesn't match the university's majors. This situation exists in every university. Inner Mongolia University is the best university in the Inner Mongolia Autonomous Region, but engineering is its weak point. Large industrial and mining companies will definitely recruit very few people here.
