It’s the season of job-hopping for "Golden Three Silver Four" and the number of recruiting places has shrunk due to the impact of the epidemic. However, Internet companies such as Ali, Tencent, Douyin, and Kuaishou have accelerated the pace of talent recruitment. Based on the editor's many years of actual experience, I have compiled a list of interviews with these big companies, hoping to help you find out and fill up the vacancies and overcome the difficulties of the interview.
JVM+MySQL+design pattern+distributed+microservices (received at the end of the complete video)
- The JVM virtual machine has always been the hardest hit area for interviews. Many small partners are planted on it and need to be prepared carefully. The high-frequency test points are as follows: JVM basic concepts, runtime data area analysis, in-depth analysis of JVM objects, such as: class loading principle, parent delegation model, source code analysis (key), JVM optimization, garbage collection, efficient concurrency, etc.
- In MySQL Internet companies, the most commonly used database is MySQL, which must be mastered. First, let’s take an xmind picture, which lists the necessary knowledge points in the interview for your reference. I hope it can help you quickly get started.
High-frequency test points in the interview: MySQL index, architecture, lock, transaction, sub-database and sub-table (focus), clustering, performance analysis and optimization (difficulty)
3. In the area of design patterns and design patterns, interviewers are more likely to ask themselves Familiar with which design pattern, if necessary, let one or several handwritten.
4. Basic characteristics of distributed transactions, basic principles of distributed transactions, use scenarios of distributed transactions, caching, Redis, Zookeeper (key), distributed lock implementation, breakdown, avalanche (key)
5. Common frameworks for microservices (Spring Boot, Spring Cloud, Dubbo, Netty), service governance, load balancing (focus), service fault tolerance protection, service invocation, API gateway service, service tracking (difficulty)
In response to these knowledge points, the editor has collected a set of good explanation videos, which are very dry, specifically:
Video 1: "Brother Zhan takes you to create the most stable knowledge graph" Video 2: "Seven days of MySql training camp" Video 3: "Big coffee takes you in-depth analysis of the principles and characteristics of distributed transactions" Video 4: "Service governance of microservices" , Load balancing"
