foreword
Today, what I want to share is my own growth experience. I am 27 years old this year. After graduating from university, I entered a small company in Shenzhen. I will not mention the name, but I am familiar with it. I have stayed in this company for 2 years, and it was not until this year that I had the idea of changing jobs.
Everyone has the dream of a big factory. After staying in a small company for a long time, there is no pressure to feel that people will become decadent, and there is no sense of oppression. Among these big factories, I chose Ali. "Youth, vitality, and passion" are the adjectives I hear most about it, so I resolutely hope that I can show myself on this stage.
The following share the interview questions of Ali’s automated testing in this interview. In addition, I also made some summary of my interview. The summary contains some learning methods and materials. Due to the space limit, I will only show you the catalog and part of the content.
Ali won the Offer on three sides, with a fixed salary of 21k (technical questions, excluding HR questions)
First side:
- Tell us about your automation testing experience and project experience.
- Talk about your understanding of Selenium and Appium, as well as your application experience in actual projects.
- What is BDD (Behavior Driven Development)? How do you use BDD in your projects?
- How to realize the sustainability of test results, that is, how to monitor test results and give timely feedback to relevant personnel?
- What difficult problems did you encounter in the project? How to solve it?
Second side:
-
Tell me about your understanding of performance testing and your experience in actual projects.
-
Talk about your understanding and application of load balancing.
-
How to judge whether a system has high availability?
-
How to design a highly available and high performance system architecture?
-
Introduce your understanding of microservice architecture and its application in actual projects.
Third side:
- Tell us about your understanding of security testing and your experience in actual projects.
- Talk about your understanding of the OWASP TOP10 vulnerabilities and how to prevent attacks from these vulnerabilities.
- If a system had a security breach, what steps would you take to address it?
- Introduce your understanding of DevOps and how to practice DevOps.
- How do you handle emergencies and high-stress projects in your day-to-day job? Please give an example.
In the three-sided technical interview, I think I have a relatively clear understanding of automated testing, performance testing, and security testing, and have some practical project experience. I also understand the concepts and concepts of microservice architecture and DevOps. At the same time, I will also look for solutions when encountering problems at work, and continue to learn and improve.
By participating in this interview with Ali's 21K automation test engineer, I felt the company's emphasis on technology, and at the same time realized my own shortcomings, such as the need for in-depth study and mastery in performance testing and security testing. I will continue to work hard to improve my technical level, and I am willing to contribute my professional knowledge and skills to the company.
I was able to pass this interview thanks to my cousin who works in Ali . As his little old cousin, after he understood my situation (almost started with the basics of Java), he directly gave me a network disk and said: "Go, here is everything you need, don't come to me, I'm ashamed!".
In the disk is a set of PDFs of necessary documents for software testing interviews.
