Preface
The gold three silver four job-hopping seasons of the workplace are here again. The difference is that this year is "colder" than previous years, and the form is more severe. You may hear or see some information, that is, many companies are optimizing layoffs. For job seekers, the interview is a hurdle. Many people are afraid of interviews. Even veterans who have worked for many years may still have interview anxiety.
These topics are my previous interviews and I was asked in the interviews with first-line Internet companies such as Baidu, Xiaomi, LeTV, Meituan, 58, Cheetah, 360, Sina, Sohu, etc. Familiarity with the knowledge points listed in this article will greatly increase the chance of passing the first two rounds of technical interviews.
Due to the large number of interview questions involved, the length of the space is longer. Based on the frequently asked questions involved in these interview questions, I have summarized and made a roadmap for advanced learning. Share with everyone, there is a free way at the end of the article!
1. Know what it is and what is its use
I believe that when many people are studying, they will find a complete set of materials on the Internet or buy a book to study, but the result is too much content, can't remember or half of the learning feels difficult, so they give up, let alone I have no way to start writing code.
And a better way is to not rush to buy books before learning, buy materials, first understand what the language or knowledge does, why this is there, what problems can be solved after learning, what jobs can be done, and it The history of development, so as to ensure that we learn the latest knowledge and have a general understanding of the future work direction.
After having this general understanding, decide whether you need to learn this knowledge.
2. Construct a mind map of knowledge
If you decide to learn this knowledge, you are here to construct a mind map of this knowledge. It can clearly show the knowledge structure of a language. We can compare the knowledge points on this mind map for targeted learning.
As for the production of mind maps, you can refer to the book catalog and some training websites to cover all the knowledge points of this knowledge as much as possible.
The following is my mind map of Android:
3. How to obtain information
First of all, you need to know what are the big cows of the language you want to learn. Start with a big cow. Look for books written by him, blogs and public accounts to find what you need. The so-called famous teachers make good students, you have to know that sometimes you Learning is not your problem!
Secondly, look for the official website and excellent community related to this knowledge. Visiting the official website and the community can increase your skills.
At last
For many junior and intermediate Android engineers, if they want to improve their skills, they often grow up by themselves. The unsystematic learning effect is inefficient, long and helpless. It’s normal to be discouraged after a long period of time, with huge time cost and effort, without seeing the desired effect.
Therefore, you must find the best way for you to learn, and have a way of thinking. Otherwise, you will not only waste time, but also delay future development.
If you are stuck at the bottleneck of lack of learning resources, then just in time I can help you. The above knowledge notes are all free to share. If you need to get knowledge notes, you can click on my GitHub to get them for free.
