In most cases, the growth rate of the tester's personal skills is much faster than the growth rate of the company's size or business. Therefore, job-hopping has become the most common vocabulary in this industry.
A few days ago, I saw a friend leave a message saying that when he was interviewing the test development engineer of Byte , he tortured his soul for three hours and unfortunately died.
The more I think about it, the more regrettable it is. Looking back on the interview process, I summed up a few points, and found that the main reason for the failure of the interview was that the interviewer did not give the answers the interviewer wanted for a few key questions. Thus lost this precious opportunity.
He was deeply impressed by the following questions, so he left me a message:
- Based on your work experience, tell us about your understanding of quality assurance?
- The difference between non-relational database and relational database, talk about their advantages?
- Are there any mature solutions in terms of automation, and have you done any secondary development?
- If the quality department needs to customize a quality system platform, what issues will you consider?
In the final analysis, the testing industry is also a technical position. The technology is constantly updated, and the requirements of enterprises are getting higher and higher. It is even more necessary for us to improve our business capabilities and constantly master new skills. When we have better job opportunities, such as bytes, how to prepare?
Below I will share the preparations before the interview from the following aspects.
1. Position yourself
First of all, you must position yourself, what stage you are now, whether it is a junior post, intermediate and senior, advanced, or expert level. Under normal circumstances, you will be a beginner when you have just started working for about a year, and you will be an intermediate if you work hard to improve yourself in about two years, and an advanced or even expert level in three to five years. The premise is continuous research.
2. Combing knowledge
Because I position myself as an automated test engineer, as the saying goes: interviewing and repairing aircraft carriers, working with screws. The interview considers various aspects. For testing, there are mainly the following aspects to prepare: interface automation testing, building a testing framework, web automation, and APP automation. Of course, after sorting out the knowledge, you have to read some interview scriptures to see the latest questions asked by various manufacturers. In fact, after preparing the above things, if the foundation is good, it will take about one month, and if the foundation is not good, it will take at least 3 months.
As the saying goes, do not fight unprepared battles, only when you are prepared can you achieve good results in the interview process.
3. Preparation of resume
Resume is a stepping stone, and HR receives many resumes every day. How can a resume be eye-catching, and can grasp key information at a glance: basic personal information (name, phone number, email address, graduate school, etc.), work experience, skill points, and some highlights (such as the sixth-level certificate, awards, etc.). The resume should be concise and well-organized. After writing your resume, you should update your resume on the recruitment website.
4. Various channels of interview opportunities
(1) Friend referral: In the circle, you must first meet some friends. Employees of various manufacturers can add friends through Maimai, or add friends through technical exchanges, so as to understand the dynamics of friends and ask them to help recommend them. Of course, there are two ways to find referrals. The first is to ask a friend to recommend a position, and ask him to ask if there is a shortage of people in the group. The second way is to find it by yourself. Under normal circumstances, the company's recruitment will display the link to join us on the official website, and you can see the job information here. The second recommendation is that you find a job yourself, send it to a friend, and ask him to recommend the job directly. There is usually a bonus for referrals.
(2) Help from headhunters: I recently listened to a course "How to Effectively Improve Your Competitiveness in the Workplace". I think the teacher said a very good sentence. Don't reject headhunters, and treat headhunters as your partners. The headhunter knows the recommended company and the current market better than you. There are also many ways to find headhunters. The first is to ask your friends if there are any reliable headhunters you have cooperated with. The second is to find a lot of headhunters like Zhaopin, Liepin, and Boss Zhipin. After you update your resume, a headhunter will contact you.
(3) Recruitment website: Internet recruitment is on the hook, boss, and Zhilian. The resume is updated on the website, and then it can be delivered. Here we need to see whether the resume delivery is effective. If no one checks your resume for half a day, then there is something wrong with your resume, and you should revise it in time before submitting.
5. Skill reserve
Automation/Performance/Security (Must be able to program) - Intermediate and Senior Test Engineer
Possess testing and coding capabilities to improve testing efficiency and software quality.
Below is an example of automated testing.
- Choose a programming language to learn: java, python, ruby, etc.
- Understand automated testing, automated testing tools, web/app/interface/pc automation basics.
- Framework ideas, project practices and processes.
After a few years in a functional testing position, I would start to feel anxious.
At work, I feel the limits of my growth. Except for the more and more familiar business, the work is also little by little, and there is no progress in other aspects.
I want to change jobs and raise my salary, but I feel very lost and powerless, because the value of my whole body is here.
I want to improve myself in the process of work, and move towards high-paying automated testing, performance testing, security testing, etc.
Of course, automated testing tools can also automate, but there are pros and cons.
Test Development/Performance, Security Test Specialist (must be able to program) - Senior Test Engineer
Test development, with testing and coding capabilities, to improve test efficiency and software quality. Both development and testing are fine.
Strong development capabilities are required to go deep into the code layer. Generally not directly involved in testing work.
- The secondary development of the testing framework and testing tools better meets the testing needs of the company's products.
- Conduct unit testing or assist in development and unit testing to control product code quality from the development stage. Quickly mine issues during subsequent iterations.
- Develop test tools and platforms, improve test efficiency, simplify various tests, and quantify test results for the test team. Such as performance testing platform, interface testing platform.
Test supervisors, managers and supervisors - career development and promotion stages
Strong testing and programming skills as well as adequate management and communication skills are required. If you only have enough testing capabilities, you can't hold the development team.
You need to let yourself clearly understand the following questions after the interview:
- What products does this company mainly promote, and are you interested? After all, only those who are interested will be willing to learn more about it;
- How many tests does this company currently have, what are they responsible for, and what is the current depth of the overall test;
- What kind of test did you enter this company specifically, whether it is a functional test, a stress test, or an all-rounder;
- How does the enterprise management consider the career planning and future development of testers.
Regarding the above 4 points, you may say that during the interview, some companies are unwilling to tell you the answers to these questions. Yes, I have also encountered this kind of company.
But ask yourself the other way around, if the company can't answer your questions during the interview, would you dare to go to such a company? Are you really willing to go? Is it just for the salary in front of you? I hope everyone will think about it.
Analysis of byte interview questions
1. Based on your work experience, tell us about your understanding of quality assurance?
This is a comprehensive basic knowledge question, which tests your experience after working in the testing industry for several years, whether you have testing thinking, and clearly defines your position. Can you talk about how you think the test should be done? How to measure quality? How do you focus on software quality improvement and help the team quickly iterate on high-quality delivery
2. The difference between non-relational database and relational database, talk about their advantages?
I believe I don’t need to repeat the importance of the database in testing work. You need to understand the principles of common relational databases and non-relational databases , and summarize the differences between them
3. Do you have any mature solutions in terms of automation, and have you done any secondary development?
Test engineers cannot do without a keyword, "automation", and automated testing techniques will be used more or less in any type of project. Regarding front-end and back-end automation technology, is there a complete set of testing framework and technical system? In the understanding of the open source automated testing framework, there is a certain development thinking, can be packaged, and the secondary development on the open source framework. Being able to flexibly build a test framework suitable for the team according to the project is a watershed in the ability of a test engineer
4. If the quality department needs to customize a quality system platform, what issues will you consider?
To be honest, if the interviewer asks such questions about the test platform, you may not be able to bear it. Anyone who has done test development should know that the construction of the test platform, except for technical difficulties. How do you think about advancing this work? After the test platform is developed, it is a big problem to promote and operate this platform in the entire test department. From the perspective of a functional tester, if you use an immature test platform for testing, if you increase your workload, it will not be of much value to your own work and technology, and generally they are not very active in cooperation. The test platform How to promote operations is a difficult problem. You want everyone to feel the difference between using and not using this test platform.
