Unity Developer Interview Preparation Guide

Custom game developers generally use one of two pricing models: fixed-price or time-and-materials. Knowing up front what model a developer uses will prevent you from costly surprises when time comes to pay the bill.

Neither model is necessarily any better or worse than the other. Which one is best for you is determined by the following factors, among others:

☛ Do you have a fixed budget, or can your budget accommodate a development fee that is totaled up after the project is completed?
☛ Do you expect to make more than minor changes to your game specifications once development has begun?
☛ Are you providing the developer with complete specifications and user stories, or will they need to help you develop those?

If your dreams don't relate to the job closely, make sure you highlight aspects of the job that will help develop the skills that will help you with your dreams. Ideally, you want your dreams to relate strongly to the career path you're interviewing for though.

A typical C# program consists of a namespace declaration, a class, methods, attributes, a main method, statements, expressions, and comments. A potential example for printing “Hello World” to the console is detailed below.

using System;
namespace HelloWorldApplication
{
class HelloWorld
{
static void Main(string[] args)
{
Console.WriteLine("Hello World");
Console.ReadKey();
}
}
}

Encapsulation is a classic object-oriented design principle that reduces coupling between objects and encourages maintainable code. It involves enclosing objects within a logical package by limiting access to implementation details. In C#, this is accomplished through the access specifiers—public, private, protected, internal, and protected internal.

One of the best ways to answer this question is clearly articulate three points that demonstrate how articulate you are (and in a sense show that in a live setting) - for example: "I would say I'm articulate because one, I typically gather my thoughts before speaking, two, I organize my thoughts well, and three I'm concise when making a point.

You could discuss the company's vision, culture and solutions/services as reasons for wanting to join it.

Structs are used to create structures, a value type that is used to represent a record. Structs play a similar role to classes, which are a reference type in C#. Since structs are value types, they are allocated and deallocated on the stack or inline in containing types. This generally makes structs cheaper to allocate or deallocate than classes, which are reference types. Reference types are allocated on the heap and garbage-collected, which tends to take up more resources. If the instances of a type are small and short-lived, it makes sense to define a value type using structs.

The opposite is true when it comes to boxing and unboxing. A value type can get boxed when it is cast to a reference type or some other interface it implements. Because boxes are objects allocated to the heap and deallocated via garbage collection, too much boxing and unboxing of a value can negatively impact performance. Reference types like classes are preferred in these situations.

The difference between dynamic and object type variables has to do with when the type checking takes place during the application lifecycle. Dynamic type variables handle type checking at run time, while object type variables handle type checking during compile time.

Most situations are "fixable" - the ones that are not are typically related to business ethics (someone is cheating the company, someone is stealing, etc)

As you consider Unity game developers for hire, keep in mind that all experience is not equal. A game developer with 20 years’ experience is not necessarily more qualified to develop your VR game than one with 15 or even 5 years under their belt. The field is ripe with developers who have spent a decade or more creating games for desktops or consoles, but who have yet to crack the nut on mobile or 3D gaming. On the other hand, a unity game developer who has spent the last 5 years creating mobile games with experience in Unity might be well-qualified to write your next 3D action-adventure game for iOS.
