How to prepare for Ali technical interview

In the spring season, Alibaba's spring recruitment interviews are in full swing. I believe that the students have also made a lot of preparations for the interview. So, what should I pay attention to when participating in Ali's interview? Today, we specially invited Uncle Yong, the senior final interviewer, to give the students the most practical interview tips.

Guest profile: Uncle Yong, senior algorithm expert, 5-year school recruiting officer, worked in Taobao, Alimama, Search, Youku and other departments, the main research direction is large-scale distributed machine learning algorithm, multi-modal interaction Search Recommender Systems, Algorithmic Game Theory.

Q: When looking at a resume, what parts do interviewers pay most attention to?

A: Mentors, laboratories, and research directions will all pay attention. As well as his papers, we will download and read them in advance, and prepare questions in advance. For other information, we will also see if there are extra points. In terms of details, the name of the mailbox shows that some students attach great importance to details. TIPS: The most critical information must be written on the first page of the resume, and the resume should not be too long.

Q: Having interviewed so many students, what advice do you have for interviewing students?

A: There are many basic points of the interview, and some small problems that many students are prone to make. I will summarize a few points and share them with you:

1. Don't be late, this is at least respect. The same is true for interviewers.

2. Prepare your resume. Practice expressing your own highlights, including technical/personal highlights, and avoid ad hoc language.

3. Respect the facts and answer truthfully. Each student is good at something different, and the interviewer's style is also different. If you ask yourself something you don't know, please don't try to force it, just answer truthfully.

4. Peace of mind. When faced with a stressful interview, don't try to provoke a PK atmosphere. In the interview process, the ultimate goal of the interviewer is to help the interviewer to find the best solution to the problem. Be yourself and practice more often.

Q: What are the dimensions of the interview? How should students prepare?

A: Ali's employment philosophy is extraordinary people, ordinary minds, and extraordinary things. We expect people to be intelligent, optimistic, sturdy, and introspective. Here's an example from technical students:

Computer students, we pay more attention to the basics. The company has a complete process system to train an engineer, and the interview is more about basic quality inspection, such as probability, matrix, etc. No special preparation is required, but the basic knowledge still needs to be reviewed.

In addition, we look more at the path of your thinking, the tools and methods of thinking, how you respond to problems, and some soft skills are incorporated into the process. Of course, we also examine the potential of the students. Our own project experience, papers, etc., we will first confirm the authenticity of this part of the inspection, and will pay more attention to the details. Don't write other people's projects into your own projects. Once you find out, the consequences will be serious.

In addition, Coding ability is a must, it is recommended to practice, and we have speed requirements. During the interview process, the interviewer will be asked to write code online and synchronize the process in real time. It mainly examines coding style, accuracy, and proficiency. After all, no interviewer will use someone who is technically incapable of working with a team.

Q: Is education a threshold for recruitment?

A: We only consider heroes based on ability, not education. In the interview process over the past few years, we have found a phenomenon: many excellent students will take the initiative to understand and pay attention to the ability items required by the company in their daily study, and continue to shorten the distance between themselves and the target value through self-study. This is a very good trend.

Q: What factors will cause students to fail the interview?

A: We will not pass a student because of a lack of ability. The interview is a step-by-step affirmative process, not a negative one.

Usually interviewers will ask at the end, do you have any questions for me? In fact, what the interviewer wants to know is whether the classmates know the position/department/company, what kind of questions you have based on the information you know, and how to ask high-quality questions in this link, and it also reflects whether you attach importance to this interview. Unfortunately, there are not many students who can answer this question well. The last opportunity to ask questions is an opportunity for him to show his comprehensive ability, but many people regard this as a part of "confirming" the interview results. There are also students who take questions to the interviewer, or are obsessed with how to answer a certain question, completely forgetting that the interview is to show themselves, not to learn and communicate, nor to PK.

Q: What should students do if they encounter special circumstances?

A: The rhythm of the entire interview is jointly created by the interviewer and classmates, so there needs to be a clear sense of rhythm. For some questions, students do not have any ideas, or feel that the meaning of the question is not clear. They must confirm it clearly and ask the interviewer for confirmation. If the on-site status is not OK, be sure to say NO instead of catering to the interviewer. For example, the quality of the phone calls is poor. What we want is to show ourselves, and what the interviewer does is to help students show their best selves.

Q: Tell me which classmate you interviewed, impressed you the most?

A: In 2018, I interviewed a classmate who has joined my team. During the interview, he mentioned his living habits, and he still has a lot of ideas about managing his time. The degree of self-discipline is surprising. After joining the job, this classmate did the same. Every morning from 6 to 9 o'clock is his study time. Every morning, I read at home from 6 am to 8 am, and after I arrive at the company at 8 am, I continue to read for another hour, rain or shine. He finished his studies, and other talents just arrived at the company. In his spare time, he also devoted himself to the publication of working papers, and just voted for 2 papers. Business-wise, he is now the backbone of our team. From the observation of him, it is not difficult to find that excellent students basically come from a high degree of self-discipline.

Q: What was the worst interview you've ever had?

A: I once interviewed a class of candidates. During the 2-minute self-introduction, the candidates were eloquent, without focus, and all the questions would diverge. The whole interview process kept showing off myself, but I didn’t get to the key points of the question. The whole interview experience was really bad.

Q: Many students are confused about how to choose a position. What advice do you have?

A: Try to know what the future career development of this position is like and whether you have the stepping stone of the position. There are a lot of internal push information from different departments of Ali, and you can find relevant senior brothers to ask. At the same time, you can do some assessments to see if you have enough awareness of yourself.
