一. 背景

2014年6月30日离开微软新加坡，第二天随即加入现在的公司，之后一直忙碌着公司的新项目，权限系统、以及旧项目的维护与重构，整体来说一起都比较顺利，每天都忙碌、痛苦并快乐着。

由于前面几个系统的顺利开发完成并上线，所以忙里偷闲，恰巧最近公司突然来了一个在我看来非常大且持久的项目，面对挑战，我希望能把它顺利的接下来并做大做好，遂希望招聘几名志同道合的.NET程序猿。 二. 招聘信息

　　具体招聘条件：

    Bachelor degree in business, software engineering, or computer science.        
    Experience creating ASP.NET views in MVC/Razor utilizing CSS and jQuery/JavaScript.
    C# .NET development in Framework 4 or newer.
    Experience with WCF web services or Web API.
    Familiarity with Microsoft Unit Testing tools, including MS Test and MS Fakes.
    Experience with source-control management systems, particularly Microsoft TFS.
    Demonstrated ability to make informed decisions quickly and leverage communication abilities to implement them.
    Any experience or knowledge on MVVM Framework (Angular.js or Knockout.js) will be a big Plus.

　　工作地点为新加坡。 三. 项目相关信息

自从加入公司后，做完了两个比较大一点的项目，其中也完善了一些基本的架构设计及框架，所以这次的新项目希望能复用之前的一些设计成果。 架构设计图：

01_Client：存放UI相关的项目，比如Winform, WPF，ASP.NET， Silverlight，ASP.NET MVC或者相关的Web Model及View Model项目。
02_Hosting：存放与Service相关的项目，可以是Direct Service，Remoting Service，Web Service，WCF Service或者Web API Service 。
03_Domain：业务逻辑相关的所有实体以及操作（根据OO的思想设计类以及类之间的关系）。
04_Infrastructure：非业务方面的功能框架 （Data，Common，DataContract，AOP， IOC，Logging，Encryption，Email）。
05_Database：数据库项目（包含所有数据库脚本，方便开发，部署以及维护）。
06_Tests：所有测试项目（数据访问测试，框架测试，业务逻辑测试，服务测试以及View Model测试）。
07_ReferenceLibs：项目相关的外部引用。
08_Tools：一些简单的工具，方便开发，测试以及部署。

组件及部署图：

执行序列图

调用Service之前需要调用Service Adapter，然后根据项目配置来决定调用WCF Service，Web API Service 还是直接DLL引用：

四. 对项目的期望

为了项目的可维护性及扩展性，希望项目能具有以下特性：

Organized：如果系统组织比较好，可以起到事半功倍的效果。
Encapsulated：对功能，结构，数据进行有效的封装，会使系统维护变得更加容易。
Reusable：对常用功能以及组件进行有效的封装，可以使系统变得结构清晰且方便维护。
Extensible：在设计系统的时候，如果很好的遵守OO的设计理念（OO的五大原则SOLID），即使系统做得很大，也会像火箭一样直冲云霄！
Replaceable：在很多时候我们需要考虑到系统，组件或者功能的可替换性，因为需求是会变的。
Testable：做到系统的可测性，会大大帮助开发以及维护，对团队开发以及分工协作起着非常重要的作用。
Loose Coupling：隔离耦合是架构设计必须要考虑的一个因素，如果系统不能做到高内聚、低耦合，那么在维护，升级，新功能开发方面就会是一场噩梦！
High Performance：高性能是系统设计必须重视的要点，用户不可能忍受简单页面加载超过十秒，也不可能接受页面操作频繁卡死的情形，所以在架构设计的时候必须从数据库，逻辑，服务以及UI进行合理的优化。
Scalability：如果能做到前面的几点，那么我有理由相信你的系统一定具备Scalability。
Enjoy Your Life：最后一点也是最重要的一点，不要忙碌于重复的码农工作，喝杯咖啡，享受代码，早点回家，陪老婆、陪小孩，环球旅游，享受生活！

五. 面试题目

之前在网上看到一个比较有意思的面试题，做完之后才发现可以通过这道题考察很多方面的知识点，遂将其做了一些简单的改编，用以面试或者基础考察。

其实面试题目比较简单，主要考察最基本的算法、面向对象及项目经验： Solution Implementation: Meeting Track Management

Suppose you are planning a big programming Meeting and have received many proposals which have passed the initial screen process but you're having trouble fitting them into the time constraints of the day -- there are so many possibilities! So you write a program to do it for you.

• The Meeting has multiple tracks each of which has a morning and afternoon session.
• Each session contains multiple talks.
• Morning sessions begin at 9am and must finish by 12 noon, for lunch.
• Afternoon sessions begin at 1pm and must finish in time for the networking event.
• The networking event can start no earlier than 4:00 and no later than 5:00.
• No talk title has numbers in it.
• All talk lengths are either in minutes (not hours) or lightning (5 minutes).
• Presenters will be very punctual; there needs to be no gap between sessions.

Note that depending on how you choose to complete this problem, your solution may give a different ordering or combination of talks into tracks. This is acceptable; you don’t need to exactly duplicate the sample output given here. Test input:
