Recently, a friend went to Byte for an interview . The interview took about 20 days, including 4 rounds of telephone interviews, 1 round of written tests, 1 round of supervisor video interviews, and 1 round of hr video interviews.
According to him, 80% of the people will fail in the first round of interviews . If he hadn't prepared well before the interview, he probably wouldn't be able to last through the next few rounds of interviews.
In fact, in the first round of telephone interviews, in addition to some regular self-introductions, they were asked about some basic professional knowledge. The main purpose was to screen out some people with weak foundations , so as not to waste everyone's time. The questions asked mainly related to the following aspects:
basic interview questions
- Self introduction
- Introduce the projects in your resume
- Share a most impressive bug
Basic theoretical knowledge
- How is the interface automation framework built in the project?
- How to decouple dependencies between interface automation use cases
- Difference between HTTP/HTTPS, Redis data type?
Regular hr digging questions
- Proportional distribution of developers and testers in the previous company
- Why are you considering changing jobs?
- Career plan for the next three years
People who come to interview, look at their resumes, have an average of 3 years of work experience, but the average level is very disappointing. In the interview, it doesn’t look like the kind of self-confidence that has been around for several years. If you don’t mention testing tools, you don’t know much about the basic technologies. APP automation, etc. are asked three times, and they all stay at the basic method level of interface testing. Advanced automation questions are even asked one by one, and the latest developments in cutting-edge technologies are not paid attention to.
However, the salary requirements of these people are all close to 22k, and they have a few years of experience during the discussion process, which feels very high.
One in particular left a deep impression on me. I have 3 years of experience in my resume, and all I did were small program display projects. During the interview, I kept emphasizing how powerful my technology was and how it was reused in the original company. I asked some details . , all are manual, almost no automation.
In the end, I recruited 2 modest and pretty good ones who can be considered as helpers. I talked about this with a few friends, and they also felt the same way. People are impetuous, and few are willing to do technical work in a down-to-earth way.
Due to the influx of these unqualified testers who think they are excellent in large numbers in the market, most companies have to lower their expectations, but the truly capable testers are basically not affected, and it is still easy to change jobs. If you are dissatisfied with your current job and do not have enough experience, you may wish to calm down and study further.
No matter what technology is hot or not, learning is uninterrupted. It is the kingly way to sharpen technology while young. Otherwise, you will not be able to eat much if you want to be young in this career of programmers. Year. However, wanting to improve is one thing, and how to improve effectively is another. I have been working for nearly ten years, and I have also supervised many interns and fresh graduates. Many young people are really hardworking in their studies, working overtime and working hard, but they are almost too late, and the methods are still wrong.
