What should I pay attention to in the interview of artificial intelligence technology?

With the resumption of work of various enterprises and companies , Job seekers can also start preparing for interviews . Here, I'd like to talk about how to prepare for an interview for an artificial intelligence technology position . The content of this interview guide is divided into two parts , One part is to prepare for professional interview , It includes the basic knowledge of naturallanguageprocessing 、 Basic knowledge of machine learning and programming code ability . The other part is the guidance of interview skills , For example, introduce yourself 、 Ability demonstration and interview communication .

What should I pay attention to in the interview of artificial intelligence technology position ?

One 、 Professional competence preparation

Talking about artificial intelligence , We have to mention naturallanguageprocessing . It can be said to be the core technology to help the further development and application of artificial intelligence , Therefore, the basic knowledge of naturallanguageprocessing must be well reviewed . For example, regularization 、 Generalization needs to be understood . besides ,Dropout Principle and use of 、 Over fitting problem 、 Activation function 、BP Back propagation derivation 、 Gradient descent and gradient disappearance 、 Loss function 、Word2vec 、 optimization algorithm 、 Evaluation index of model 、SVM deduction 、CRF、attention、 Text classification problem 、 Sequence tagging problem 、Seq2seq、 Data imbalance and so on are all questions that will be involved in the interview .

Another core technology of artificial intelligence is that machines need to learn , The knowledge points we need to review and prepare for this chapter have a logical meaning \ Linear regression \ Logical regression 、 Naive Bayes 、 Decision tree 、HMM,CRF、XGBoost、KNN、K-Means、SVM、Boosting、Bagging difference 、RNN、CNN 、LSTM ( principle )、LSTM and GRU Apply scenarios and differences respectively . These are common questions in the job interview of artificial intelligence technology .

in addition , Artificial intelligence technology posts also have certain requirements for programming ability , Generally speaking, one or more programming languages are required (C++、Python、 Java、Scale ..ect). Therefore, we also need to brush more interview questions related to programming . such as , How in length 100W Find the smallest number K Number ? Longest common subsequence ( Melon seeds ), Two points search , Valid symbols ( Sina 、 Cheetah ), Recursive and non recursive traversal of binary trees . Besides , Some companies ask math questions , Like a diagonal matrix 、 Derivation, etc .

Two 、 Interview skills preparation

1、 Self introduction.

About self introduction , We must be concise . At the time of self-report , May include name 、 School 、 Major and other basic information . Then the most important thing is personal experience , You must make it clear what you have done . The project description should include the project name + Specific contents of the project . There are a few small tasks ( classification 、NER、 Relationship recognition 、 Summary generation ..etc), Highlight the importance of your task , And what kind of tasks are you responsible for , Introduce your method implementation , How does it work ? And how to improve it , And then what is the effect of your design ? This is to highlight the process of your research and thinking . Then you'd better talk about your understanding of the other company , It can be combined with the projects you have done .

2、 Communication

During the interview , Just be sincere and friendly , Just be confident and generous . To know that the interview is not a single choice question , It is more like a two-way choice between the interviewer and the interviewer , So you don't need to lower your position , There is no need to be overly nervous . In addition, in the whole interview assessment , It is necessary to distinguish whether the problem can be solved or not , Avoid getting caught up in the interviewer's questions . Try to communicate more with the interviewer , Repeatedly determine the questions you want to ask during the interview . If the interviewer doesn't answer your professional questions , You can gently ask him to change the question .
