The following situation is summarized for your reference.
1. For students with development experience, learning big data is relatively easy. For example, if you are doing JAVA development now, then you can switch to big data and do JAVA big data development. You only need to learn the big data framework and related big data technologies, supplemented by certain project exercises, and you can basically work; If you are doing Python development now, you only need to learn the big data framework and related technologies, and then you can engage in Python big data development in combination with related projects.
2. If you have no foundation and average learning ability, you will be slower to understand concepts. For example, when you learn JAVA object-oriented, these students will be confused, but as long as you are willing to pay, ask more questions and think more, you will get ideal results.
3. Zero-based learning ability is very strong, such as 2 1 1 985 college graduation, which is relatively easy to learn. In our big data training class, more than 50% are such students. I have to say that they have a strong learning ability and learn everything quickly, not just programming.
The first one has development experience, and they will take the initiative to learn; The third kind of learning ability is strong, and they believe they can learn it. But the second is their lack of self-confidence and hesitation.
Among the three kinds of people, the second type of students is also the majority. If you want to change careers, here are three suggestions for your reference.
1. Don't hesitate to learn first. Find the study materials first and learn from the beginning. Only when you really start learning will you know if you can learn well.
2. Recruit a bachelor's degree, learn big data, and find big data development work. At present, enterprises in first-tier cities have bachelor degree requirements for big data development engineers.
3. College degree, studying JAVA and looking for JAVA development work. If you don't have enough education, learn JAVA well first and find a job in JAVA development. If you are interested in big data, you can do JAVA development for 2 years first, and then switch to big data to make up for the shortcomings of academic qualifications with development experience.
I hope it helps you ~
