2021 Annual Summary: Transformation

recall

It feels faster this year, and it’s time to write a summary for the year. Let’s take a quick look at this year

Leaving the company where he worked for five years. Joined a larger company
The rented house was also changed, and the rent skyrocketed
Output content
- The output of the article is terrible, only single digits.
- The question and answer is not as good as last year, only 500+, but it can be regarded as one question a day.
- Sharing, research, and other internal output were still being done in the first half of the year, and the frequency of job changes decreased in the second half of the year.
If you travel, I only went to Xiamen this year

think

Here are some thoughts this year 🤔, share with you the mental journey of changing jobs~Hahahaha

For old club still find many of dismay, there are a lot of friends at a five-year, milk is also very thought of the boss (Chi brother superb, Hu Du Son, dare dares, super drink tons tons tons ) , And a little brother who is big in one hand😏

In fact, changing jobs for a long time. , there are many reasons for leaving, and there are many reasons for not leaving. In the end, walking took the upper hand. Why don't you guess?

Don't go:
- brothers : five years, only four years of college, and not at school last year. Eight hours of work, including overtime, it’s more time than I spend with my wife🐶
- leads : The boss is very nice. Being with the right person is sometimes very important, to have power, welfare, and growth. Zhige also took special care of the calf. (Do you want to mix with Zhige? Ubay also recruits the front end. Blow up)
- Comfortable : Can be regarded as an old employee, with a younger brother under his hand, so he can do his job well.
- Money 161c1308fcc096: Salaries, year-end bonuses, outstanding employees, etc. are all in place. Although they are not
go:
- company : The company has been there for five years, and the size has not changed much. And it’s getting more and more curled up, I get off work almost every day at 10 o’clock (of course, my brothers leave early, just a few small people in charge have endless meetings. late, sooner or later, cool ) Then why am I How about changing to a larger company roll?
- promotion : Although the salary is in place, I feel that the promotion is over. Compared with my boss, I am really convinced in management. The gap between everyone in technology is almost the same, and everyone has their own familiar fields.
- volume : performance is so much, I eat others but not, I am confident that I can eat. But everyone has been working together for a long time. If you should leave, maybe because I am gone, can the company change when other people grow up?
- Age & anxiety : Really, Beijing too TM anxious. It's thirty, if you don't change it, how many years can you eat this bowl of rice? Do you have a chance to change in the future?
- Recruitment : Recruitment is really difficult, there is no fresh blood.

Based on the above thinking, I think I need to change to a larger one to meet my promotion needs, learn about the management systems of other companies, and cross the 35 threshold.

Speaking of this, I remembered yesterday’s video with my mother. She said: What is the difficulty of your work? What is the tiring? It's much easier than farming. Isn't it just learning? How tired can learning be? I don't feel tired from (She has never planted land, but because of the age, she may have suffered a little bit when she was young. Now she is a painter) Brothers, how can I refute her?

Gluten

I guess my brother’s favorite is gluten. I met with four interviews (Kaishou, Jinshan, Byte, Didi) and all passed the interview. Guess where I joined?

In fact, the two roles "161c1308fcc19b Interviewer, Candidate interviewer at Ubay for more than two years, but I didn't recruit a few people and seduced myself away.

I think the success of my interview is also related to my understanding of the interviewer’s mentality

Interviewer

This content is also included in the transfer of work to them before leaving the job, so take this opportunity to organize it. An interview for front-end development

Let's first understand what recruitment must do, and what is the purpose?

Recruit a meets the standard , so what is the standard?
- Educational qualifications (the company’s mandatory requirements) need not be discussed. Generally, HR can screen out unqualified resumes
- Technology (ability to work, potential, shortcomings, special skills) basically recruit people in these directions, must have characteristics in one direction . It is nothing more than insufficient manpower, or reserve for new business, or want to acquire some new technology. negative example of 161c1308fcc241 is what you can’t do, what you eat is not left
- character. This part generally is a normal person don't think it is funny, there will really be abnormal people😈. It usually matches team personality, such as "aggressive", dare to fight, be active, and strive for reasons, such as "peace", calm and calm. is not to take the initiative 161c1308fcc260
- communicate.
How to judge whether a person's skills are up to standard? the content that the brothers are interested in .
- Basic knowledge (3 questions). HTML, CSS, JS front-end moat. For example, how to calculate css weight? What are the html block-level tags? What are the JS data types?
- Logic skills (2 questions). Code snippets or simple programming questions. For example, what is the result of the closure? For example, find the average? Like sorting?
- Advanced knowledge (2 questions). New technology and business expansion. For example, realize that axios supports cache function? For example, write a polyfill for some new methods on Array.prototype.
- Expand knowledge (2 questions). It's a little hard to say here. Business difficulties, industry implementations, and related technologies are all possible. For example, the network: https, http cache. For example, what content, principles, and loaders can webpack do. For example, performance optimization.
- Algorithm (1 question). Simple and medium difficulty. Looking at the previous performance, let's examine the abstract ability again.
- Past experience (2 questions). This is generally to see the level of understanding of the previous business, such as whether you have participated in the development of core functions or just made a fight. It is also to see if the candidate can stand alone in the project already done. You can also look at expression communication, summary reports, and so on. It can be regarded as an comprehensive direction of .
How to wring out the water? ( really learned candidates ignore this group, the interviewer focuses on this group ) I do not discriminate training course , after all, I will also pay to learn something online. But many training courses will have a lot of water.
- Basic knowledge survey. Generally, Express will ignore these things, such as html and css. For example, some basic computer knowledge hard disk and memory (this is a bit of a spoof 🐶).
- Business logic becomes logic. This link is generally the focus of training, but it is often also a weakness. I said before that the is to find a (liver, this word is very good, I will not change it), then go directly to a CURD. Of course, you can test the business scenarios here, and use fancy language to blur the inspection points.
- It cannot be done with the help of search engines. For example, for scenario questions, the current project is slow to load, how to optimize, the candidate will definitely memorize the answer, but at this time the interviewer asks the candidate to answer the specific steps
  - (Network troubleshooting abnormal resources, cli -report, webpack --profile --json> stats.json)
  - LH score. What are the indicators. The optimization direction of each indicator?
  - Flame illustration. How to check and how to analyze?
  - How to solve it after analysis? What is the corresponding method for each question?

The above are probably some examples I communicated with them before. The specific example should not be this, after all, I have many questions.

Here we begin for the interviewer to set up quasi-purpose (xian) equipment (jing)

candidate

In fact, interviewing this thing is to prepare more and brush up the questions. interviewers also hope that the candidate is a well-prepared person .

Let me talk about how to prepare, although I don't remember much.

Prepare:

Ready to project in advance, you will have playing scratch . Write a bunch of resumes, what do you know how to do it yourself, look for something for yourself?
we take care of the ?

Example 1: Interns, training class features: permissions, login, registration. If you understand, you know, this thing is not changed once for thousands of years, and a new project is nothing more than copying a set. There are also cookies, storage, and headers that are silly and unclear.
For example, you really did, and with the Storage Access, Headers pass token, then you should look up the Internet advantages and disadvantages of the program , relevant knowledge
- Now that the token is used, the token has expired, how to update it? Does token have logic like renewal? How is it displayed, in that part?
- What APIs does Storage have? What types of data can be stored? What is the difference between localStorage and sessionStorage?
- What is the difference between token and cookie schemes? What are the characteristics? Are there any scenarios where the token scheme is problematic?

Example 2: unfamiliar with this project, the project forget that I just did a page, these projects do not write , it does not seem to ask a not ask a 🐶.
The item we wrote on the resume, must understand every word in , so you don’t panic when you ask.

Base:

You have to know this thing, don't you know how to do it for many years of old front-end?

Here are tips for 161c1308fcc5be, usually visit (please make money, if you don’t make money, can you send a copy of the surrounding 😜) visit the Q&A area, you can filter the questions by category.
you want to learn, you can see the answers, and if you want to show your craft, you can see the unsolved ones.

You can also follow some big guys and websites

css:
- Zhang Xinxu. css is compatible with this invincible, I will take a look at it for a long time.
- CoCo. The various effects are amazing. The community is also very active
js:
- Wakagawa. There are activities such as reading the source code together. The community is also very active
html
- mdn. There is a document in this block and it's over

algorithm:

Then swipe it. One day. In fact, if you can't answer, the interviewer will usually give you ideas.

I suggest that you first understand the common data structure, then from simple to difficult , and then brush the high-frequency questions. It doesn't matter, you can look at the solution, and do it a few times after reading the solution. Learn the new by reviewing the past, you can xxx

Of course, there are also some people who will take some crooked paths , such as writing a non-optimal solution first, and then slowly optimizing it to the optimal solution, so as to waste time. I don't recommend , because it may affect your rating, in case you encounter a difficult interviewer, you will hang up.

Promotion, rank division

This is also something that has been considered more this year. One is that I was responsible for the interview before I left, and I wanted to divide this work before I left. The other is that the basic clear rank (p6, p7, 2-1, 2-2, etc.), and there will always be a rating when going out for an interview.

Generally speaking, the technical division is divided into the following ranks:

Rank (Technical)	Rank (Ali Technology)	Rank (Ali Management)	Rank (byte technology)	Compare working years
Junior Siege Lion	P4	-	1-1	Interns, fresh graduates
Intermediate Siege Lion	P5	-	1-2	Freshman, 1-3 years
Advanced Siege Lion	P6	M1	2-1	2-5 years
expert	P7	M2	2-2	3-7 years
Senior expert	P8	M3	3-1	5-10 years

Of course, although the level is like this. However, the gold content of each company's rank is different. generally only represents the level within the company, and only a very small number of companies' rank standards can be recognized by the industry.

Generally speaking, there are the following statements about rank and promotion:

Elementary, Intermediate, Advanced, Architect
Be a kid, lead people, lead projects
Development to management
From end B to end C
Edge function to core function to money related business.
The task is becoming more and more illusory, from a clear goal task to an idea.

TODO: Just write a little bit. There is an urgent need. Next week, I will fill up the ability requirements of each rank, and you can also help fill up.

Technical rank	Technical depth and breadth (professional)	Leadership, influence (general)	Communication, coordination, analysis (general)
Junior Siege Lion	Understand the capabilities used, is instructed	-	-
Intermediate Siege Lion	Proficiency in using the abilities used, was instructed	-	Arrange work reasonably
Advanced Siege Lion	stand-alone completion module	s	Break down the problem, put forward a point of view, think independently
expert	independent completes small projects	Department, community	Land execution, independent solution, cross-team collaboration
Senior expert	leads the team complete medium-sized projects	Industry, Division, Community	Resource assessment, knowledge system
