Interview questions architect software

They are sometimes similar but grow from different needs. YAGNI grows from a too much future anticipation, overzealous workers if you may. KISS is a strategy that tries to counteract human tendency for design creep. 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. Unlike relational database property of Strict consistency, eventual consistency property of a system ensures that any transaction will eventually not immediately bring the database from one valid state to another.

This means there can be intermediate states that are not consistent between multiple nodes. Eventually consistent systems are useful at scenarios where absolute consistency is not critical. For example in case of Twitter status update, if some users of the system do not see the latest status from a particular user its may not be very devastating for system.

For example a banking transactions system can not be using eventual consistency since it must consistently have the state of a transaction at any point of time. Your account balance should not show different amount if accessed from different ATM machines. 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 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. In a distributed environment communications failures can happen.

If communication between the transaction manager and a recoverable resource is not possible for an extended period of time, the recoverable resource may decide to unilaterally commit or rollback changes done in the context of a transaction. Such a decision is called a heuristic decision. It is one of the worst errors that may happen in a transaction system, as it can lead to parts of the transaction being committed while other parts are rolled back, thus violating the atomicity property of transaction and possibly leading to data integrity corruption.

Because of the dangers of heuristic exceptions , a recoverable resource that makes a heuristic decision is required to maintain all information about the decision in stable storage until the transaction manager tells it to forget about the heuristic decision. The actual data about the heuristic decision that is saved in stable storage depends on the type of recoverable resource and is not standardized.

The idea is that a system manager can look at the data, and possibly edit the resource to correct any data integrity problems.

A portfolio allows structural architects to showcase past work samples and abilities. Candidates should ensure it has the essentials and supporting documents like:. While cleaning up their portfolios, solutions architects should remember to work on their branding.

Personal brands are unique talents that distinguish one job seeker from the other. It allows solutions architects to display their values, credibility, and personality.

When preparing for interviews, solutions architects should also compose questions they intend to ask the interviewer.

Asking questions shows enthusiasm for the hiring company. Candidates should avoid asking questions that center on themselves or their salaries. A strong closing statement can leave lasting impressions on the interviewing panel. Interviewees should affirm their interest in the vacant position, remind the interviewers of their qualifications, and finally ask for the job. Candidates may also seek clarification on the next steps after the interview.

Solutions architect interview questions and answers focus on technical, interpersonal, communication, and problem-solving capabilities. To improve your chances of landing this position, you should:. Below are five of the most common solutions architect interview questions and answers. Solutions architect interview questions and answers can sometimes touch on technical aspects. Interviewers also want to know that you can identify their organizations' specific needs and plan strategies to boost successful outcomes.

Use your answer to showcase what you already know about the company you applied to and how this information can help you determine the best implementations for creating the organization's online catalog. Example: "From my understanding of the organization, the online catalog would require a single master list of departments to provide product listings for each category. For instance, for the "engine parts and components" department, I would create a sub-catalog with product pages for each item in the related inventory.

Within each product page, I would then create sub-units, depending on the specifications of each item, like colors and sizes. Depending on the pricing structure and lead-in for online payment processing, I would then implement standard encryption code to establish secure payment architecture within the catalog payment portal.

It shows that a software architect appreciates what it means to be object-oriented at a granular level. It is more important that a candidate understands the five concepts rather than specific terms.

These are the first five rules of OO design by Martin. Understanding dependency injection demonstrates that a software architect not only understands SOLID but knows how to achieve it in a real-world scenario. Dependency injection does this by decoupling creation from usage and is important to modern coding because it reduces the frequency at which classes need to be updated just because their dependencies changed.

Software architects are responsible for developing and monitoring software systems and fulfilling complex system needs for businesses. This question allows an interviewer to learn more about what types of interpersonal traits a candidate has that could enhance their job capabilities at their company.

Interpersonal communication is important as it allows me to work with a range of professionals who have varying understandings of computer software. This is especially helpful when I need to explain the necessary time-frame for a project. I also need to have a keen attention to detail to catch coding errors and time management ensures I meet my deadlines.
