Junior Software Developers assist the Software Development Manager and design team with basic coding tasks, test procedures, and information retrieval. Junior Software Developers are entry-level coders who assist in the smooth running of the development process while improving their design skills. This is one of the more straightforward.NET interview questions you can ask. Most web developers will at least be familiar with alternative frameworks such as Laravel and should be able to discuss some of the differences between those platforms and.NET. This article will go through tips on how to ace a junior developer job interview and is written by Natasha Postolovski, a Graduate Software Developer at ThoughtWorks. You can follow her on Twitter: @npostolovski. The Junior Developer job interview process can seem a little bit scary. For some Junior. We are currently hiring a junior developer to help me out, as I have more projects than I can currently manage. I have never hired anyone who wasn't a friend or at least an acquaintance. I have a phone interview with the only applicant that actually stood out to me (on paper), but I have never done this before. Software Engineer Interview Questions: Here are a few interview questions a software developer is usually asked by an interviewer. The motive of asking these questions is to analyze not only his technical skills but also to check other important skills needed for a developer.
Driver sharp ar 5620v. I worked at a couple of places where development managers loved drilling job candidates on syntax while having them write code, and it was clearly a stressful experience for the interviewee. I do not like asking specific syntax questions during interviews since most developers do not know language syntax or class names off the top of their heads.

In terms of the basic interview, I prefer to ask open-ended questions where the candidate can explain concepts and how they would attack problems. Some organizations like to give candidates tests or have them eyeball code snippets to spot problems, and I think those are good evaluation tools.

Junior Software Developer Technical Interview Questions
What are namespaces, and how they are used?
Namespaces are used to organize classes within the .NET Framework. They dictate the logical structure of the code. They are analogous to Java packages, with the key difference being Java packages define the physical layout of source files (directory structure) while .NET namespaces do not. However, many developers follow this approach and organize their C# source files in directories that correlate with namespaces. The .NET Framework has namespaces defined for its many classes, such as System.Xml—these are utilized via the using statement. Namespaces are assigned to classes via the namespace keyword.
What is a constructor?
A constructor is a class member executed when an instance of the class is created. The constructor has the same name as the class, and it can be overloaded via different signatures. Constructors are used for initialization chores.
What is the GAC, and where is it located?
The GAC is the Global Assembly Cache. Shared assemblies reside in the GAC; this allows applications to share assemblies instead of having the assembly distributed with each application. Versioning allows multiple assembly versions to exist in the GAC—applications can specify version numbers in the config file. The gacutil command line tool is used to manage the GAC.
Why are strings in C# immutable?
Immutable means string values cannot be changed once they have been created. Any modification to a string value results in a completely new string instance, thus an inefficient use of memory and extraneous garbage collection. The mutable System.Text.StringBuilder class should be used when string values will change.

What is DLL Hell, and how does .NET solve it?
DLL Hell describes the difficulty in managing DLLs on a system; this includes multiple copies of a DLL, different versions, and so forth. When a DLL (or assembly) is loaded in .NET, it is loaded by name, version, and certificate. The assembly contains all of this information via its metadata. The GAC provides the solution, as you can have multiple versions of a DLL side-by-side.
How are methods overloaded?
Methods are overloaded via different signatures (number of parameters and types). Thus, you can overload a method by having different data types, different number of parameters, or a different order of parameters.
How do you prevent a class from being inherited?
The sealed keyword prohibits a class from being inherited.
What is the execution entry point for a C# console application?
The Main method.
How do you initiate a string without escaping each backslash?
You put an @ sign in front of the double-quoted string.
What is the difference between a struct and a class?
Structs cannot be inherited. Structs are passed by value and not by reference. Structs are stored on the stack not the heap. The result is better performance with Structs.
What is a singleton?
Junior Software Developer Phone Interview Questions
A singleton is a design pattern used when only one instance of an object is created and shared; that is, it only allows one instance of itself to be created. Any attempt to create another instance simply returns a reference to the first one. Singleton classes are created by defining all class constructors as private. In addition, a private static member is created as the same type of the class, along with a public static member that returns an instance of the class. Here is a basic example:
What is boxing?
Boxing is the process of explicitly converting a value type into a corresponding reference type. Basically, this involves creating a new object on the heap and placing the value there. Reversing the process is just as easy with unboxing, which converts the value in an object reference on the heap into a corresponding value type on the stack. The unboxing process begins by verifying that the recipient value type is equivalent to the boxed type. If the operation is permitted, the value is copied to the stack.
