Lao Wang, 35, works as a tax collector in a certain place. He has been admitted to the civil service since graduating from college. He thought his life was very comfortable in a small county town. Later, at a class reunion, he met his roommate whose academic performance was not as good as his many years ago. His roommate is now working as an architect in an Internet company with an annual salary of one million. He was a little envious, and after returning home, he searched online for salaries in the Internet industry:

He told me that his life was a bit too dull now, working from 9 to 5 every day, and depending on the look of his superiors. . However, I am already 35. Would anyone still want to transform into an Internet company now?

I explained to him the current situation of Internet companies. Internet companies have been in a cold winter stage since 2018. Not to mention the epidemic this year, it is even more difficult. But Chunjiang Plumbing Duck knows that there is still a lot of job demand in the big data industry.

Of course, it’s all empty talk! I showed him some reliable news data and let him think about it for himself:

Big data graduate positions found from the Chuanzhi Podcast official website:

However, Some training institutions on the market are now using Javaee courses to pretend to be big data, and the proportion of Javaee courses is as high as 60%. Not only that, it’s already 2020, and they are still using notepads to teach big data, which is tantamount to asking students studying artificial intelligence to experience life in the Stone Age first.

According to my early research and comparison process, every institution promotes how good and complete the content of its courses is. At this time, newbies need to keep their eyes peeled. But this is more difficult for novices. We don’t understand how I know if the content is good or bad? Is it good to just listen to part of it and listen to the teacher bragging and feel comfortable? Frankly speaking, it's really hard to judge. But there is a pit here, which I think can be avoided. You can first go to the video libraries of various training institutions to compare, for example:

The conclusion I have drawn is that the content is good or bad for us. It’s best to find someone with experience to tell the difference, but you must not apply for a course that is large and comprehensive and has everything you need. Talking too much means talking too little, and talking too shallow means giving you a little more depth during the interview. If you can't answer the question, the consequences will be game over or severe salary reduction.

Technology is still about concentration, and it is better to drill deeper.

In the early days, I was worried that there were many requirements written by others in the recruitment requirements. I didn’t know what to do with this, and I didn’t know how to deal with that. Later, I found out after two or three weeks of interviews and several offers. Many companies want to recruit generalists who can do whatever they want, but in fact they know it is impossible. There are many words in the recruitment information. What actually matters is whether your core skills are qualified for the job, and whether the positioning and salary expectations are reasonable. .

Recently, I participated in an event and received a big data 8-antenna experience course. It is a real big data basic experience course, not a fake Java basics course!

Seats are limited, while supplies last! It has been personally tested to be a real activity!
