Please read these 10 suggestions first!

1、 This year, xing Bad style , Don't be naked !!

Personal information such as telephone number is wrong , The sentence in the project experience is not smooth 、 Misspelling 、 Variant character , Punctuation 、 Typesetting and other messy resumes are very common .

4、 In depth review of developed products or projects .

  • product development / The project experience should be considered as rich as possible , The key points are detailed ;

  • Highlight project advantages 、 Bright spot 、 The work and contribution you're involved in ;

  • If there's big data scale development 、 Operation and maintenance 、 framework 、 Selection experience and so on are added points .

The interviewer asked you Previous work , What's the main research ?

  • Your project or product development experience .

Relevant project experience , Work faster in a new company .

The interviewer's attention is yours Produce results , Not the process .

  • Your role in the project ?

Architecture design 、 Scheme selection 、 The product design 、 Demand docking 、 detailed / Outline design 、 Development 、 Operation and maintenance 、 Maintenance, etc .

Participated in architecture design and only CRUD Our engineers are different .

  • What problems have you had , How? ?

It mainly investigates and analyzes problems 、 Ability to solve problems .

Ask for help offline 、 Online search or help (google、stackoverflow、disscuss.elastic.co)、 Log analysis 、 Source code analysis, etc .

There is no right or wrong solution to the problem , The interviewer focuses on you How to solve the problem Of .

Look at whether you choose to escape or Grasped the nettle 、 Solve the problem .

5、 There's a personal website 、github Open source project 、 Blog 、 Open source contribution 、 Hobbies related to hobbies 、 Winning a prize and winning a place are also bonus points .

6、 Be prepared against want , prepare for the worst , Make the best preparation .

Elastic Stack The breadth and depth of knowledge should be reserved .

  • Deep cognition :

Including but not limited to : Writing principle and optimization 、 Retrieval principle and optimization 、 Performance troubleshooting and tuning 、 Cluster role division and deployment 、 Cluster capacity planning 、 The principle of inverted index 、LSM principle 、TF/RDF Scoring principle 、Lucene Related technical principles, etc .

  • Breadth cognition :

Including but not limited to :CRUD、 retrieval 、 polymerization 、 Custom participle 、 Custom rating 、template、mapping、 Secure backup 、 Cross cluster search 、 Cluster environment construction 、kibana Visual analysis 、Logstash N Synchronization and processing of multiple data sources 、Spark、Kafka、Redis、Mysql、Oracle、Mongo Data docking, etc 、Beats Data access, etc .

7、Elastic authentication It's a bonus , But don't mention it many times , One eye-catching position is enough .

Many big companies don't necessarily have golfers now Elastic Solid technology , Especially certified players , This is the truth ;

But basic things can be learned by others with the same or less time , It's also true !

Active learning The ability and consistency of Continuous learning It can be emphasized that .

8、 To strengthen the underlying principles 、 Source code learning and thinking .

Some online video tutorials are very good , For building total Elastic Systematic cognition is useful , But it's not enough .

Consider expanding : Super brother source code principle book 、 Geek time search principle 20 speak 、lucene book 、 Algorithm book tutorial !

9、 Solid data structure and algorithm basic skills , The ability to analyze and solve problems with ease is an inspection point .

How to deal with the scene of interviewing a large factory but without a large factory ?

such as : Ten billion of big factories 、 Hundreds of billions of data 、 Dozens of clusters 、 Each cluster has hundreds of nodes and so on. It is very difficult for small factories to have large clusters .

  • Go to the community and look at other people's problems 、 And try to answer questions ! because : Other people's problems , It's very likely that you'll meet .

  • Small factory ball friends go to the community to see the problems of netizens all over China and even the world , Can effectively avoid “ limited outlook ”! I think I have almost mastered it , It's a long way from it !

  • Look at Alibaba cloud 、 Tencent cloud bottom sharing blog , Empathize with your weaknesses ! Strengthen the study with pertinence !!

Modification of the underlying source code , Small companies may not be able to use , but , Doesn't mean it's useless . Look at the sharing of some big companies , On expanding cognitive boundaries 、 It also helps to expand the idea of solving problems !

10、 Be confident

You're not confident , God can't save you !

Don't be afraid of your favorite factory , Don't be afraid of the interviewer .

Only a very small number of interviewers make things difficult for candidates , Ask small and trivial questions that you don't even know , To show how powerful you are .

The vast majority of interviewers are standing in the team to recruit new people 、 Interview candidates from the perspective of technical communication .

Most of the interviews will appear “ Interview to build rocket 、 Working screw ” The situation of , But the interview stage is the screening stage , It can't be avoided .

Even if the interviewer throws questions, he or she won't , Remember to try to answer with the previous knowledge , Answer is better than no answer , Better not to answer than to pretend to understand .

Elastic Stack It's normal for technology stack to have blind spots , Don't be pessimistic , Go home and study it carefully to make up for the blind area knowledge points and the surrounding expanded knowledge points ......

Wave your sleeves , Keep getting ready to go , Prepare for the next interview ! Until I get my heart offer until !
