It has been half a year since my social recruitment , Although I didn't go to chengdachang , But I'm still very satisfied with my present job . As a friend said , The criteria for evaluating a person should be multi-dimensional , Big factories are not the only way to measure ability , Not going to a big factory does not mean that the interview experience has lost its value . That's why this article , I hope my experience post can bring you some help ~

Personal situation

Shangcai benshuo , Major in financial information engineering , Working as an algorithm engineer in a second-line Internet enterprise 2 More years . No contest, no thesis , The post of delivery is NLP Algorithm engineer .

resume

Resume is a stepping stone to interview , It is absolutely right to spend more time polishing your resume . Resume mainly includes basic personal information , Education experience , Work experience , Paper published , Several aspects of professional skills . Because I have no experience in publishing papers , So my work experience is my focus . The first thing I did was polish my resume , Make sure you pass the resume screening test .

You can find a sample resume to fill in your own content , Make sure the structure of your resume is clear , The content is refined , The project experience is related to the position , It's best to send it to a friend who has experience as an interviewer . But in fact, the projects I have done in my last company are not so close NLP Algorithm , Want to interview NLP There are certain difficulties in the position of algorithm engineer . I remember when I finished the first version of my resume , Send it to a friend , He said directly that my project was too simple （ Although direct, it is also true. Hahaha ）. Then I told him I couldn't help it , This project is like this , There are no sophisticated algorithms . He said it would not work , I can't pass my resume , The project has to be redone . At that time, I heard this sentence , I was shocked , Project redo ？？？ Can you still do this ？ Besides, it doesn't take a lot of time ？ Although but , It really has to be done , Otherwise I may not find a job for months . During that time, I collected data every day after work , Run the model , Optimization model , Finally, a passable resume was formed . Project experience suggests STAR Write in principle , Project background 、 Task type （ classification 、 Information extraction 、 Dialogue, etc ）、 Action taken , The results achieved by the project , Personal gain .

Now go back and reflect on your last job , There are many points that can be improved . The first point is the courage and opportunity to change jobs . In fact, I have long realized that the project of this position does not match the direction I want to engage in , But I didn't have the courage to change jobs immediately , And stay with the hope that the future will be better 2 year .2 Years later, I finally realized that there was nothing I wanted , But at this time, I have less time than others to work towards my expectations .

The second point is the polishing of the project . For a variety of reasons , Some of the projects will go nowhere , Maybe it's because the effect is not good ; Maybe it's because the project is not very important , The product didn't follow up . From the perspective of job hunting , It is not appropriate to include such a project in your resume , But don't write , There may not be much to write . So in the course of the project , Be sure to consult relevant materials as much as possible , Try different methods , When you encounter difficulties, you should have the courage to ask for help , Don't give up just because you can't . After all, a person's power is limited , Admit your shortcomings , Learn to rely on others , And doing so will make your progress faster . For example, you do a text summary project , Not reading a few blogs , Just try a few methods , You also need to track the latest developments in the field of text summaries , It's best to look at the review paper , Have a more comprehensive understanding of . After model training , If the effect is good , Think about why it works , Because the data quality is high , The applicability of the model is high ？ If the effect is not good , We also have to analyze whether it is a data problem or a model problem , Or the training process .

interview

Generally speaking, there will be some maladjustment at the beginning of the interview , So it is necessary to find a company with two matching positions to be familiar with the interview process . In this way, you can quickly enter the interview state , And accumulate some interview experience , Know what interviewers like to ask . Study the job description carefully before the interview , Company background , Know what company you are interviewing for , What does the post do .

The interview mainly includes self introduction 、 Code of hand tear 、 Project introduction 、 Post related knowledge investigation, etc . In addition to the basic information , You can also talk about your own advantages , Job related / Anything irrelevant . Hand tearing code mainly depends on the accumulation of previous problems , I won't go into that , The key point is to brush more questions and summarize more , Know how to draw inferences from one instance , And have a good code style （ This is rarely mentioned , But code style is very important , Anyway, I've seen them hang up because of bad coding habits ）.

Project experience must be the focus of the investigation , It is different from school recruitment , Social recruitment generally does not ask too much basic knowledge , Ask questions mainly around the points involved in your project experience , In addition, you may ask about the knowledge points involved in the position and the basic knowledge of the field 、 Frontier model , For example, you have a dialogue post , The interviewer must be very concerned about your knowledge accumulation in the field of dialogue . Again from NLP From this general direction ,BERT And its variants 、Transformer、T5 And other models must be mastered , The frequency of being asked is very high .

The basic point in the project interview is Be able to clearly and skillfully explain the projects they have done , This can be prepared in advance , Write a manuscript , Just practice a few more times . Put the project background 、 Purpose 、 Role in the project 、 The approach taken 、 The final effect is clear , Then the interviewer will ask some specific questions about the project ： Why use this model / Method , What is the principle of this model , Have you tried any other methods , What is the latest development direction and frontier model in this field , Furthermore, it is possible to ask relevant models in a divergent way , There are also difficulties encountered in the project 、 How did it work out 、 What does the individual gain from the project 、 Understanding the business also needs to be prepared in advance , These are common interview questions . If the model goes online , I will also ask questions about engineering and launching . There are also very detailed questions , For example, how to calculate the cross entropy . I also met an interviewer who asked if I could do better now , What are you going to do . Here, in addition to your algorithm research ability , They are still examining their learning ability 、 Business understanding 、 Language skills 、 Ability to solve problems, etc , It's a very important part .

There are also a few problems that I have encountered with high frequency listed here for your reference

• Understanding of the company and the position applied . This requires taking time to collect data in the early stage , Analyze the position , This part is to judge whether you have prepared the interview carefully , Whether you really want to enter this company , In this position .

• Career development plan . It mainly examines your understanding and positioning of yourself , Professional knowledge , Knowledge of the company , And your attitude towards job hunting .

• Why change jobs / Leave your last company . Don't speak ill of your last company , The common answer is to look for a bigger development platform ; In the last company, I encountered a bottleneck , Want to jump out of your comfort zone , Let yourself have a bigger breakthrough .

• Any questions to ask . The question you ask shows what you care about , What do you care about , So avoid asking about salary 、 Overtime and so on , Ask about the size and status of the team , Expectations for this position, etc .

• There are also some questions related to personal experience . For example, I majored in financial information engineering , I am often asked why I didn't choose to go to the financial industry , And choose NLP This direction of the algorithm . My post in Shanghai is Hangzhou , I will be asked why I want to go to Hangzhou . These problems vary from person to person , Just don't answer too strangely ~

An interview is a mutual interaction , The process of investigation by both parties , It's not just the interviewer who examines the interviewer , It is also an opportunity for the interviewer to inspect the interviewer . Experience the company culture from the interview process , The skill level of the interviewer , The matching degree between the position and oneself , And the matching degree with their own career development direction are all questions that interviewers need to consider . Sometimes I will meet an interviewer who is not so friendly , Don't think it's your problem , It may be the interviewer's question , It may also be that Tao is different , Just don't conspire .
