Coding Interview Test: What Kind of Programmer Are You?

A coding interview is used for hiring purposes. The interviewer will ask you a series of questions and test your skills, so it is important to understand how the type of interviewer can affect your performance. Knowing your coding personality enables you to maximize your strengths and avoid common pitfalls in programming. The coding interview is a classic job interview. The interviewer will describe a problem and ask you to write some code to solve it. Your task is to present the most elegant, fast and correct solution with minimum complexity. The interview section is used to find out if you meet the requirements of the company, while the second part is performed to test your programming skills and ability. Your goal is to write a good implementation of the algorithm or solve the problem in a minimum amount of time. 

How Coding Interview Tests Will You What Kind of Programmer Are You?

A coding interview test is a job interview that tests your skills, knowledge and experience. It is an interview that is used to find out if you have the needed skills to perform well in the position at hand. Your goal is to find out if you are good enough for the position and what kind of candidate they will be looking for. This test is used to find out more about the company, their goals, and the culture in which they work. Most companies require coding tests before they select you for a position. They want to make sure that you meet the needs of their company and will be a good fit for their company. The skills you need to know for a first coding interview will vary from language to language.

1. Surface knowledge :

All of you have had first programming experience and maybe you will be asked about it. You will be tested on how well you know the language you are using. This test is to see how familiar you are with the language and its basic elements. The interviewer will give you a small problem and see how you solve it. This test is to make sure that you know the basics of the language and have knowledge to write a small program. You will be asked about some basic concepts in the programming language, such as loops and a function.

2. Programming Logic:

The interviewer will ask you what methods should be called and when they should be called in order to solve the problem. The interviewer will also ask about how you can call certain methods automatically and what made you pick this approach. They will also ask you to write a few basic functions and classes. This will test your skills in using control structures, such as the if statement and loop. You will be asked questions about the differences between variables and data types, how variables are used to store information and how objects can be created for these variables.

3. Object Oriented Programming:

You will be asked how you can implement different methods and objects. You will be asked to show how you can implement different classes and their methods. The interviewer will ask whether you have used an aspect and what new features it will add to the program. You will have to discuss how you can optimize your program and what the best approach is when it comes to minimizing the run time. This test will require you to be familiar with some advanced concepts in programming such as threads, memory optimization and a compiler. 

4. Language specific skills:

You will be asked questions about the systems used in the language and architecture of a program. The interviewer will ask what is needed for running a program on a specific system. You can also expect questions about the memory leak, how an object is created and deleted from memory, what you know about garbage collection and how it works on different platforms and how you can improve its performance.

5. Encapsulation:

You will be asked how you can encapsulate and hide information from the outside world in order to control what the outside world can do with it. This test will test your knowledge and skills in hiding information from the outside world and making it available only when needed to make the program run faster. You will also be asked about data types, such as arrays and structures, that help keep data close together thus making programs easier to write. It is used to contain information that is related and access it as a unit for efficiency and size. This type of Java test online will require you to have a good knowledge and understanding of programming principles.

6. Object oriented design:

You will be asked to solve a few problems in a modular way so that each part of code has a clear purpose. You will have to show how you create classes that contain all the objects needed for different functions. You will be asked about polymorphism and how it can be used to avoid code duplication and maintain data consistency. You will learn about inheritance and abstract classes that are used to create a more flexible program. The interviewer will also ask about code organization, such as the structure of the files and the use of comments for keeping track of what goes where.

7. Software Quality:

You will be given a small task, such as creating a program with an error checker that is known to have issues with malformed files. You will need to implement a solution that resolves these issues in order to test your skills in software quality assurance. You will have to decide what methods you can use to implement a good quality checker. This is a good test to see if you are the kind of programmer who knows how to write good code that will solve the problem efficiently. You will be asked questions about how data can be used in order to track errors and prevent them from happening again. 

8. Algorithms and data structures:

You will be asked questions about different types of algorithms, such as sorting and searching algorithms. The interviewer will ask you which data structures you know and how they are used. You will have to explain the way different algorithms work in order to solve specific problems. You will have to show how the data needs to be arranged in order to solve a problem efficiently. The interviewer will ask you what is the best algorithm to use for a specific situation and what is the worst.
