Internship experience sharing | Ant interview experience sharing

When I went online recently, I saw that many students of the 24th class have already interviewed for summer internships in big companies such as Byte, Ant, and Alibaba Cloud. Everyone is still very good, and I also thought of the details of my internship search last year. I plan to share it next.

I hope to give a little help to the students who are preparing for internships or want to prepare in advance.

How do you learn

your strengths and weaknesses

experience:

1. Not only to learn the technology itself, and what problems this technology solves, but also to understand the ideas behind the technology, such as which technologies have similar ideas to those you have learned before.

2. If you don’t know the question asked by the interviewer, you can honestly say that you don’t know. If you have the opportunity, you can also say, if you let me design, how should I design it, and why should I design it this way. How to answer depends mainly on whether the interviewer wants to examine the question itself, or whether he wants to understand the depth of your knowledge through the question.

3. The principles and ideas of the technology itself, as well as the advantages and disadvantages of the technology, and what problems the technology solves are also routines that are often investigated in interviews.

4. Sometimes the interview will be very casual, and sometimes the interviewer will hit you. At this time, you have to choose to look at it, and correct it in time if it is helpful to you. Don't affect your state of mind.

5. For me, the interview is the fastest way to improve my level, and the level refers to the level of job hunting.

In fact, if you have no internship experience, you will lose some if you go for an internship. In this case, you can improve yourself from the four perspectives of basic knowledge, algorithm questions, personal blog, and projects.

Ok, this is the end here. This article mainly talks about the difficulties that students who have no interview foundation will encounter, my own learning progress at the beginning, and how to better deal with interviews. Later, I will introduce my interviews with Alibaba Cloud and Ant last year. The actual combat experience, I hope it can help everyone.

In the future, we will continue to update the summer internship interviews of companies such as Tencent, Keep, Microsoft, Nvidia, and CICC.
