C#

History:

C# (pronounced "C-sharp") was developed by Microsoft in the late 1990s, led by Anders Hejlsberg, the same engineer who worked on Turbo Pascal and Delphi. The language was originally called “Cool” (C-like Object Oriented Language) before being renamed C# in 2000. It was created as part of Microsoft’s broader .NET initiative, which aimed to provide a modern framework for building applications that could run on the Windows platform and eventually across different systems.

The core purpose behind C# was to combine the power and performance of C++ with the simplicity and productivity of Visual Basic, while incorporating the safety and structure of Java. Microsoft wanted a language that was modern, type-safe, object-oriented, and easy to use for building web services, desktop software, and later mobile and cloud applications. C# was designed from the start to work seamlessly with the .NET Framework, providing developers with a robust standard library and tools for rapid application development.

Over time, C# has evolved significantly, embracing features like asynchronous programming, LINQ (Language Integrated Query), pattern matching, and functional programming constructs. It is now one of the most widely used programming languages in the world, powering everything from enterprise software to games (via Unity). Its purpose has grown beyond Windows, with .NET Core (and now .NET 5/6/7/8) enabling cross-platform development on macOS, Linux, and the cloud.

5. Methods and Parameters:
   Understand method definition, return types, and parameter usage.
6. Arrays and Strings:
   Test knowledge of handling basic collections and string manipulation.
7. Basic Error Handling (Try-Catch):
   Test understanding of simple exception handling.
8. Compiler questions:
   The candidate is asked to write code that must display a certain output.

Results, videos and documents:

At the end of the exam, the website will generate a PDF file containing your candidate’s results. The document will provide a detailed analysis of their performance and offer valuable insights, including:

• Candidate Score: Total score and individual results for each question
• Global Statistics: Overall exam data such as the average score, number of candidates who passed or failed, average time taken, etc.
• Time Tracking: Time spent by your candidate on each question
• Performance Breakdown: Highlights of the candidate’s strengths and areas that need improvement

A video of the entire exam will also be available. One part of the video will display the candidate’s webcam, while the other will show their screen. This allows you to verify that the candidate did not cheat during the exam.

If you include this exam as a requirement in a job offer, the job offer page will provide additional insights once all candidates have completed the exam. The page will display:

• Ranking: A leaderboard showing candidates ranked from highest to lowest score
• Average Score: The average score of all candidates who have passed the exam
• Summary: A textual overview of candidate results, giving you a clear snapshot of their overall performance
