1.深呼吸,不要紧张,其实它很容易。唷! 2.当你第一次接到面试通知时,试着把会见订在一整周(五天工作日)后。你可能倾向更早些的面试 以便“把事情做完”。请不要屈从于这样的本能反应,因为你需要时间来准备你的 面试 。(当然,如果面试官坚持一个早些的日
1.深呼吸,不要紧张,其实它很容易。唷!
2.当你第一次接到面试通知时,试着把会见订在一整周(五天工作日)后。你可能倾向更早些的面试 以便“把事情做完”。请不要屈从于这样的本能反应,因为你需要时间来准备你的 面试 。(当然,如果面试官坚持一个早些的日期,那么请爽快地接受。)
3.做好准备工作。上网查找与公司有关的每一篇文章。不要仅仅读过这些文章,还要研究,仔细分析它们。基于你所挖掘的信息,制作一张你自己的、对公司的提问的“主要列表”。
4.进行更深更广的调研。查找公司的网站,获取公司以往的年报,检阅它们,如同身临其境。购买这一领域的商业出版物,了解公司同行所作所为。一定要在你的问题列表上加入一些竞争者的信息,为你在面试中提问做好准备。
5.从公司里找到任何你能联系上的人,并从他们那里挖掘一些对你即将来临的面试有帮助的信息。询问公司最近发生的活动;查明公司的管理结构;找出面试官在公司的位置。如果你不认识公司里的任何一个人,那么请找公司同行中你认识的人,从他们那里得到公司的消息。晚上出去和他们喝喝酒,如果有必要,请他们吃顿饭。不要忽视这个重要的步骤!
6.熟练掌握本书的问与答。更重要的是,稍微改变一下答案以对应你的实际情况。(你绝对不会希望自己像“教科书”一样,你更愿意表现出你的特色,展现最多的自我魅力。)把本书中一些你觉得可能问到的问题与答案,加入到你自己设计的“主要列表”中。
7.写下你的目标。不会那么容易就得到工作吧,你会问是的,当然会,如果我做得好。以针对该公司的方式写下你的目标。“我的目标是成为ADR公司客户联络部的副部长,我希望得到年薪,(通过你对公司的调查,你将知道理想的工资水平)。研究表明写下目标能帮助人们加快实现目标。尝试一下,你又能损失什么呢
8.每天复习你“主要列表”中的问题、答案、公司的历史、具有竞争力的见识,直至你面试前的15小时为止。如果有必要的话,在你的家里或公寓中把自己关在一个安静的房间里,问自己问题,然后大声回答。许多候选人都忽略了这一简单的步骤,其实它可以帮助你预先记忆你的回答。你会想,这样听起来是不是会像录音一样不会的。当你真正熟悉了你的材料,在面试中你才能更自然地完成面试。
9.在面试前预先决定好你穿什么服装。这可以避免你到最后一分钟时去做艰难的决定。确定你的服装都已经放好,且它们适合工作的要求。等到面试那一天时,要洗好澡,刷好牙,清理好指甲和头发。带一卷清香薄荷糖在身边,以防万一要用。
10.在面试前的15小时,请停止学习,试着放松自己。如果你喜欢,做做瑜珈或听听你喜欢的曲子。请不要喝咖啡,以保证你能睡个好觉。

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.

SQL commands in MySQL can be divided into categories such as DDL, DML, DQL, DCL, etc., and are used to create, modify, delete databases and tables, insert, update, delete data, and perform complex query operations. 1. Basic usage includes CREATETABLE creation table, INSERTINTO insert data, and SELECT query data. 2. Advanced usage involves JOIN for table joins, subqueries and GROUPBY for data aggregation. 3. Common errors such as syntax errors, data type mismatch and permission problems can be debugged through syntax checking, data type conversion and permission management. 4. Performance optimization suggestions include using indexes, avoiding full table scanning, optimizing JOIN operations and using transactions to ensure data consistency.

InnoDB achieves atomicity through undolog, consistency and isolation through locking mechanism and MVCC, and persistence through redolog. 1) Atomicity: Use undolog to record the original data to ensure that the transaction can be rolled back. 2) Consistency: Ensure the data consistency through row-level locking and MVCC. 3) Isolation: Supports multiple isolation levels, and REPEATABLEREAD is used by default. 4) Persistence: Use redolog to record modifications to ensure that data is saved for a long time.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
