If you’re gearing up to land a new job, take a look at these most frequently asked interview questions for senior software engineer positions.
Applicants for both on-site and remote senior software developer jobs can expect a slew of questions covering technical ability, topics you should be familiar with, and problem-solving.
This post covers over 20 senior software engineer interview questions and answers to help you prepare for and ace the interview.
Here is a comprehensive guide to the top interview questions for senior software engineers. Let’s dive in.
Some of the OOP limitations are as follows, and you’re free to add yours on top:
There are two types of abstractions in traditional object-oriented programming: classes and objects. An object is an abstraction of a real-world entity. In contrast, a class is an abstraction of an object or another class (think of it as a generalization).
As a result, as the degree of abstraction grows, entities become more generalized, and as it drops, entities become more particular. The level of abstraction is comparable to a scale spanning from more particular entities to more generalized ones.
Because prototypal object-oriented programming only has one form of abstraction, prototypal object-oriented programming languages are considerably simpler than classical object-oriented programming languages (objects).
Objects in prototypal object-oriented programming languages are abstractions of real-world objects (which are called objects) or other objects (known as prototypes of the objects they abstract). As a result, a prototype is a generalization.
In prototypal object-oriented programming languages, objects can be created from scratch (ex-nihilo) or from other objects (which then become prototypes of the newly created object).
You can't talk about CDy and CDt without talking about continuous integration (CI).
Senior software developer interview questions often ask about the top configuration management tools, including:
The list goes on. However, it is always recommended that you mention what you know well in case there are follow-up questions.
A monolithic application is constructed as a cohesive entity, whereas a microservices architecture comprises smaller, individually deployable services.
Microservices are not a panacea, but they alleviate many issues for developing software and businesses.
Because a microservices architecture is made up of pieces that run separately, each service may be built, upgraded, distributed, and scaled independently of the others. Software upgrades may be carried out more often, resulting in higher dependability, availability, and performance.
They are therefore perfect for big data apps, modernization and phasing out of legacy apps (for example, those typically upgraded by Salesforce developers), real-time data processing, adoption of the DevOps model, multi-group developments, and other projects that require the unique benefits offered by microservices.
A code smell in computer programming is any trait in a program's source code that may signal a larger issue and thus require refactoring. Some of the common ones include:
The projected cost of redesigning software is referred to as technical debt. It results from using simple, constrained solutions during software development to save production time. To prevent this, some measures can be taken:
There are more measures to implement, with the underlying goal being the prevention of costly mistakes and decisions.
Deployment strategies are practices used to upgrade or change a running instance of an app. Some of the common types of deployments include:
The strategies fit different situations and are often chosen based on how they impact the system and end users.
The testing pyramid is a model that categorizes software testing into three forms. This assists quality assurance and development experts in ensuring improved quality, reducing the time required to uncover the underlying cause of errors, and developing a more dependable testing system.
There are three layers in the testing pyramid. The pyramid's base is used for unit testing, the middle stage is used for integration testing, and the top and final layer is for user interface and exploratory testing.
End-to-end testing is a software testing approach that evaluates the complete software from start to finish, including its integration with other interfaces.
End-to-end testing considers the complete software for dependencies, data integrity, and connectivity with other systems, databases, and interfaces to simulate a complete production environment.
It checks batch and data processing from various upstream and downstream systems and the software system, which is how the approach gets the name "end-to-end." End-to-end testing is often performed following functional and system testing.
It simulates real-time conditions by using genuine production data and a testing environment. End-to-end testing is also known as chain testing.
Test Driven Development (TDD) and Behavior Driven Development (BDD) have their own merits and demerits. When comparing the two, TDD beats BDD when it comes to:
Agile-led teams have widely adopted test-driven development, and there are many different tools to help teams get on the same page. Unfortunately, there are fewer tools for behavior-driven development since it involves communication between business and technical teams.
Application security (AppSec) is now critical to ensuring business continuity. While security is never synonymous with compliance, you should be familiar with the following application security standards to offer you minimal baselines for implementing best practices:
Sensitive data is highly confidential information that has to be kept secure and unavailable to those without authorization. Sensitive data comprises information such as people's home addresses, salaries, customer data, credit/debit card data, and information that should be protected in case of a data breach.You can prevent exposure by:
The OWASP Top 10 is a solid starting point when building secure code. A significant percentage of apps have a security issue that falls in the OWASP Top 10. They include:
SAFe (Scaled Agile Framework) is usually best applied when:
There are three main Scrum roles. They include:
Whatever it was you introduced, the methods of gaining cooperation tend to stay the same:
Whenever you have to convince others of an idea in a workplace, there are some steps to take:
There are more ways to convince people of your ideas, and they should all be leveraged appropriately to push for change.
A prototypical developer is focused on the lines of code and associated chores and is often unconcerned with the customer's demands. That's not always the case in real life, though.
The software engineering business is continually expanding, and we are increasingly meeting programmers who do not mind engaging in communication with the customer.
This strategy, it turns out, helps you build better products. Furthermore, programmers' inventiveness, innovative thinking, and expertise can prevent various challenges during development.
User research is classified into two types:
To handle high-impact decisions, you have to include everyone who will be affected by the changes you make. That is why when you are about to make a high-impact decision, you need to make sure you:
After all that, you can document the changes, implement them, and communicate relevant information to the involved parties.
A project is deemed successful if it is finished on schedule, under budget, meets the objectives, scope, and performance requirements, and is accepted by users.
People within and outside of the industry agree that contributing to open-source projects is a great way to learn, teach, and generally make the software many people rely on much better.
It is a good look on your resume and a great way to show that you have passion, given that no one is paying you to do something good. Suffice to say, it won't hurt to say you do contribute. However, ensure you avoid any awkwardness if a follow-up question is thrown your way.
