Ask the right questions to secure the right ASP talent among an increasingly shrinking pool of talent.
ASP, or Active Server Pages, is a server-side scripting language developed by Microsoft in the late 1990s. It was initially released as a component of the Internet Information Services (IIS) web server and was designed to build dynamic websites, applications, and services. ASP uses VBScript or JScript as its default programming languages but also supports other .NET languages like C# and Visual Basic.NET. The language has evolved over time into ASP.NET which offers improved performance and enhanced features for web development. This information is sourced from Microsoft's official documentation on ASP technology.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
In ASP.NET, exceptions can be handled by using try-catch-finally blocks. The try block contains the code that might throw an exception, the catch block handles the exception if one is thrown, and the finally block contains code that is always executed, regardless of whether an exception is thrown or not.
CLR stands for Common Language Runtime and it forms the heart of the .NET framework. It is responsible for managing the execution of .NET programs regardless of any .NET programming language. It provides various services such as memory management, thread management, security management, code verification, compilation, and other system services.
ASP is a server-side scripting language, while ASP.NET is a web application framework. ASP.NET allows for programming code to be written in various .NET languages like C# and VB.NET, while ASP uses VBScript or JScript. ASP.NET has better language support, a large set of user controls, XML-based components, and user authentication, with better performance than classic ASP.
The main components of .NET framework are Common Language Runtime (CLR), .NET Framework Class Library, and ASP.NET.
An ASP.NET developer is responsible for designing, implementing and maintaining web applications using the .NET programming framework. They work with business analysts to understand the business requirements and design the application accordingly. They also write code, debug issues, perform testing, and ensure that the application meets all the functional requirements.
The tech industry is constantly evolving, so it's important for a developer to be able to keep up with new technologies and changes in the industry.
Experience with these technologies is beneficial because they are often used in conjunction with ASP.NET in web development.
Understanding the principles of software design and development is important for creating efficient and effective software solutions.
Problem-solving skills are crucial for a developer. They should be able to identify, analyze, and solve problems that arise during the development process.
Good communication skills are necessary for any job role. It's important for a developer to be able to explain complex technical concepts in simple terms to non-technical team members.
Understanding the ASP.NET framework is essential for an ASP developer. This knowledge is necessary for developing enterprise-level web applications.

Early binding refers to assignment of values to variables during design time, while late binding refers to assignment of values to variables during runtime. Early binding is faster but doesn't support polymorphism. Late binding supports polymorphism but is slower.
Securing an ASP.NET application can be done in several ways. Some of the most common methods include using Windows authentication, forms authentication, and authorizing users based on their roles. It's also important to validate user input to protect against SQL injection attacks, and to use secure communication protocols like HTTPS.
HTTP Handlers are the .NET components that implement the System.Web.IHttpHandler interface and are used to handle individual HTTP requests. HTTP Modules are .NET components that implement the System.Web.IHttpModule interface and are used to handle application level events.
Caching in ASP.NET can be implemented using the Cache object. The Cache object allows you to store data that can be globally accessed within the application. It is primarily used to store data that is expensive to create.
DataReader is a forward-only, read-only cursor that is used to read data from a database, whereas DataSet is an in-memory representation of a collection of Database objects that includes tables, relations, and constraints. DataReader is faster and more efficient for situations where you need to quickly loop through the results. DataSet provides more flexibility by allowing random access to data.
At this stage, a skilled ASP engineer should have demonstrated in-depth knowledge of ASP.NET framework, proficiency in C# and SQL, and a strong understanding of MVC architecture. Red flags would include inability to articulate technical concepts or lack of problem-solving abilities.

static void Main(string[] args)
{
var numbers = new List { 1, 2, 3, 4, 5 };
var evenNumbers = numbers.Where(n => n % 2 == 0);
foreach (var number in evenNumbers)
{
Console.Write(number);
}
}
} The final few interview questions for a ASP candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
There are several ways to optimize an ASP.NET application for better performance. Some of the most common methods include using caching to reduce database hits, optimizing your database queries, minimizing the use of view state, using paging for large data sets, and compressing your content.
ASP.NET provides several state management techniques including view state, control state, hidden fields, cookies, query strings, application state, and session state.
Server.Transfer transfers from one page to another on the server side without making a round trip back to the client's browser. This provides a faster response with a little less overhead on the server. Response.Redirect is used to redirect the user's browser to another page or site. It performs trip in the client's browser, but it can be used for both internal and external redirection.
A secure login process in ASP.NET can be implemented by using forms authentication. The user's credentials are collected via a form and then encrypted and sent to the server. The server then validates these credentials against a data source and if valid, issues a cookie to the user. The user's browser then includes this cookie in all subsequent requests to the server.
ASP.NET provides several types of validation controls, including RequiredFieldValidator, CompareValidator, RangeValidator, RegularExpressionValidator, CustomValidator, and ValidationSummary.
