ChinaSoft is indeed a big company, and I learned about it on the Internet, because one of my classmates trained in it and found a good job after coming out. I used to be technically similar to me, but now I'm better than me, so I hesitate to go to training, and I'm not satisfied with my job now.
I think other training is specialized training, only recommended, not insured.
I also hope to have professional advice. If you are from a training institution, please make a detour. Thank you.
