There are too many training institutions in Hangzhou. Some of them must be reliable, and most of them are unreliable. Not recommended in recent years. Big data is difficult and self-study is impossible. If you really want to learn big data consulting or sign up for a class, the big data market has been very good in the past two years, and the starting salary can reach 8- 12k, and the development space is also very good. There is a shortage of big data talents in Hangzhou, and the future treatment will definitely get better and better with the growth of work experience and technology. I hope I can help you.
