The interview is the way of internal referral, because the pass rate of the resume of internal referral is much higher than other methods; my internal referral method is: contact a university senior who I work in ByteDance.
For online interviews, there is an online text editor, similar to leetcode, which can be programmed online. However, I was a little nervous, video interview website, video conferencing tools, please do not prepare to confirm that your network environment is good before the interview (the laptop ran out of power in the middle and I didn’t notice it), maybe it’s psychological factors that affect the quality of my interview. As a result, many simple questions were not answered well, and we still need to accumulate more at ordinary times so that we will not show timidity in the interview. Share the question with everyone.
interview questions
- The idea of the written test questions and what is the black box and white box.
- Data structure questions, here is a question about a double-linked list.
- TCP three-way handshake and how to look at it.
- Stress tests, stability tests, databases.
- The number of occurrences of a character in a string.
- Given a linked list, delete the last nth node.
- Deleting a node is nothing more than traversing the linked list to find the node in front of that node, and then changing the next point.
- First traverse it to get its length, then subtract n from the length to get the position of the node to be deleted, and then traverse to the previous position of the node.
- The process of testing.
Summary of your interview
The preparation is not enough, whether it is because of the nervousness of the video or the preparation of strength, the performance is not complete enough.
In the process of answering, I was too low self-esteem, which led to a vicious circle of incoherence.
If the individual takes the initiative to be humble, it will also trouble the interviewer.
How to Prepare for a Software Testing Interview
1. Prepare resumes (stepping stones, programmers who can't package resumes can only go to outsource)
Programmers must put more effort into their resumes, especially some words must be carefully considered, such as the difference between "proficient, familiar, and understanding" must be clearly distinguished, otherwise you will be digging a hole for yourself.
2. Understand the interview company, do your homework, and know what to ask
I also made the following summary of the interview points of the first-tier Internet companies:
Alibaba, Baidu, Tencent
Bytedance, Meituan, JD.com
3. Sort out the knowledge system and learn to infer other cases from one instance
In fact, sorting out the knowledge system is the easiest thing, but many development noobs are always at a loss. In fact, from the second point of the big factory interview point, we can summarize and sort out what we should learn and master. My method is "dachang interview points" + "working years" to sort out my next learning and development roadmap.
After that, you need to carry out targeted learning according to the key points on the road map. During the learning process, learn to draw inferences, learn to write notes, and make summaries.
Here I share some of my personal notes:
