Job Interview Questions Software Architect
A software architect is a software expert who makes high-level design choices and dictates technical standards, including software coding standards, tools, and platforms. Software architecture refers to the high level structures of a software system, the discipline of creating such structures, and the documentation of these structures. Originally published on - Never Fail Your Tech Interview Again Q1: What does "program to interfaces, not implementations" mean? Topic: Design Patterns Difficulty: ⭐⭐⭐ Coding against interface means, the client code always holds an Interface object which is supplied by a factory. Any instance returned by the factory would be of type Interface which any factory candidate class must have implemented. This way the client program is not worried about implementation and the interface signature determines what all operations can be done. This approach can be used to change the behavior of a program at run-time. It also helps you to write far better programs from the maintenance point of view.

97 solution architect interview questions shared by candidates Top Interview Questions Explain the difference between a Java interface and a Java abstract class. 2 Answers An abstract class is a generic that usually has some common methods defined that subclasses can use. However, the class itself contains one or more abstract methods that the child classes should implement. Abstract classes cannot be used directly, they must be instantiated by a subclass. Inferfacesare a template for method defition and can be adopted by any class to define a particular behavior. One key difference is that's lass can only extend one other class but it can implement many interfaces. in addition to what the Interview Candidate wrote: abstract class can contain concrete methods while interfaces can only have methods with no body.

The idea is that a system manager can look at the data, and possibly edit the resource to correct any data integrity problems. Q8: What Is Shared Nothing Architecture? How Does It Scale? A shared nothing architecture (SN) is a distributed computing approach in which each node is independent and self-sufficient, and there is no single point of contention required across the system. This means no resources are shared between nodes (No shared memory, No shared file storage) The nodes are able to work independently without depending on each other for any work. Failure on one node affects only the users of that node, however other nodes continue to work without any disruption. This approach is highly scalable since it avoid the existence of single bottleneck in the system. Shared nothing is recently become popular for web development due to its linear scalability. Google has been using it for long time. In theory, A shared nothing system can scale almost infinitely simply by adding nodes in the form of inexpensive machines.
Interview Questions for Software Architects: 1. What is the largest development team you've overseen, and how did you manage it? Tests the candidate's leadership and organizational abilities. 2. What are some pertinent questions you would ask a client to figure out their requirements? Tests the candidate's communication skills. 3. Have you ever had a major setback in the development process? Tests the candidate's ability to overcome difficulties and solve problems. 4. Has a client ever been unhappy with something you developed? How did you resolve it? Tests the candidate's interpersonal skills, and ability to resolve conflicts and issues. 5. What factors would you look at when deciding between creating a web application or a locally installed application? Tests the candidate's ability to make high-level decisions that meet the client's needs.
Q: There are eight poets, namely, A, B, C, D, E, F, G and H in respect of whom questions are being asked in the examination. The first four are ancient poets and the last four are modern poets. The question on ancient and modern poets is being asked in alternate years. Those who like H also like G, those who like D like C also. The examiner who sets question is not likely to ask question on D because he has written an article on him. But he likes D. Last year a question was asked on F. Considering these facts, on whom the question is most likely to be asked this year? Answer Answer: C Explanation: Since the examiner likes D, it means he must like C also, since the question states that those who like D like C also. Since last year a question was asked on F, who is a modern poet, this year a question will be asked on an ancient poet which means A, B, C or D Now the examiner is not likely to ask question on D because he has written an article on him. So he will ask the question on C since he likes C as well View answer Workspace Report Error Discuss
This theorem has created the base for modern distributed computing approaches. Worlds most high volume traffic companies (e. g. Amazon, Google, Facebook) use this as basis for deciding their application architecture. Its important to understand that only two of these three conditions can be guaranteed to be met by a system. Q6: Do you familiar with The Twelve-Factor App principles? The Twelve-Factor App methodology is a methodology for building software as a service applications. These best practices are designed to enable applications to be built with portability and resilience when deployed to the web. Codebase - There should be exactly one codebase for a deployed service with the codebase being used for many deployments. Dependencies - All dependencies should be declared, with no implicit reliance on system tools or libraries. Config - Configuration that varies between deployments should be stored in the environment. Backing services All backing services are treated as attached resources and attached and detached by the execution environment.
