Two sides
- 1. Introduction
- 2. Algorithm
It is worth mentioning that the eldest brother on the second side was very anxious to me, and finally made a wave of abuse. Because in the previous algorithm class, the teacher said that from a performance perspective, recursion should not be used as much as possible, and the iteration can be used as much as possible. Iteration, but the recursion written by elder brother is really concise. In addition, programming questions must pay attention to programming specifications.

hr noodles
- to chat with
- Ask the project, background, original intention, and what is responsible
- Ask why they choose their company
to sum up
- Fully prepare the data structure, brush the questions on online programming, read the basic knowledge of books, practice projects, take into account the basic computer knowledge, and the most important thing is to accumulate your own knowledge. Other aspects and question banks are just icing on the scene.
- If you adjust your mentality, the choice of the first company is the most important. Success will increase your confidence along the way
- Summarize, think, learn and improve after each meeting
- Pay attention to new technologies, pay attention to open source projects
- Work harder, only work harder than others
- I wish you a successful new year of job hunting and find a satisfactory job.

Finally, I wish you all my colleagues a satisfactory job, if you are confused about the interview. I have compiled some real interview materials, technical knowledge analysis tutorials, and exchanges and learning with colleagues to make progress together (obtained at the end of the article)
