By asking your candidate this question, you\u2019re not only offering them a nice warm-up before you get to tougher asks, you\u2019re also getting a window into their capabilities, preferences, and deeper understanding of how they\u2019ll meet the requirements associated with this position. You\u2019ll know if they\u2019re a proficient and efficient coder based on how they answer this question.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-an-answer-you-d-hear-from-a-stand-out-candidate\"><strong><em>An Answer You\u2019d Hear From a Stand-out Candidate<\/em><\/strong><\/h3>\n\n\n\n<p>\u201cI think it\u2019s important for me to be as familiar as I can be with all the relevant programming languages, as different projects and applications can benefit from different approaches to coding and the programming languages that support them. However, given the choice, my preference is to work with PHP, <a href=\"https:\/\/www.dice.com\/hiring\/recruitment\/java-developer-job-description-template\">Java<\/a>, Ruby and Python. I find they offer me the most versatility and capability across the widest swath of projects, so they wind up being my go-to languages depending on what the ask is, and what the end result is that we\u2019re looking to achieve. Sometimes Ruby is more suited to one aspect of a project than Python, or PHP is a stronger language to use for certain aspects of an application above all others, but that\u2019s why I like to work across multiple languages, so that if I can\u2019t accomplish something I want to accomplish with one of them, I can pivot to another and create what the client or company is looking for.\u201d<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\" id=\"h-2-what-is-your-approach-to-debugging-and-improving-applications-and-programs\"><strong>2.

Similarly, when a company has multiple offerings under their belt, they\u2019re always looking for ways to improve their current offerings to stay competitive and maintain their user base. Asking this question helps you gain more insight into your Back-End Software Engineer candidate\u2019s troubleshooting process, and gauges how they\u2019ll handle it if you ask them to take on the task up updating and upgrading existing applications and programs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-an-answer-you-d-hear-from-a-stand-out-candidate-0\"><strong><em>An Answer You\u2019d Hear From a Stand-out Candidate<\/em><\/strong><\/h3>\n\n\n\n<p>\u201cIn terms of debugging, I\u2019m pretty meticulous about my testing process. I use a debugging tool that goes through all of my code and helps me see where the issues are, if any. From there, I work to determine how to fix any of the issues that came up in the debugging process, and how to implement those fixes or changes in a way that doesn\u2019t affect supporting code throughout the project. As for working with existing applications or programs, I like to get a clear view of what currently works with the project before I start working with it, so I know what people like about it. From there, I can learn more about what they feel needs improving, and then craft a plan to move forward that uses the best of what currently works, and then build upon what doesn\u2019t work in a way that addresses the company or client\u2019s needs, and what they ultimately want the user to experience.\u201d<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\" id=\"h-3-what-has-been-your-most-challenging-team-project-and-how-did-you-work-through-it\"><strong>3.

This is a good way to determine whether or not your Back-End Software Engineer candidate has what it takes to work across multiple departments\u2014and in some cases, collaborate with management or directly with clients\u2014to successfully shepherd a project from conception to completion in conjunction with the entire team.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-an-answer-you-d-hear-from-a-stand-out-candidate-1\"><strong><em>An Answer You\u2019d Hear From a Stand-out Candidate<\/em><\/strong><\/h3>\n\n\n\n<p>\u201cThere was one project I had with the last company I was at where we\u2019d planned out every step through every department, and despite that, it felt like everything that could go wrong, did. Throughout the development lifecycle I worked in conjunction with the <a href=\"https:\/\/www.dice.com\/hiring\/recruitment\/front-end-developer-job-description-template\">front-end developers<\/a>, designers, and system administrators at different points to work through the troubleshooting process and brainstorm solves for the issues we were facing. We had to revise our estimates and change course a few times, which was to be expected a bit given that what we were looking to create was pretty ambitious. And yes, there were some late nights\u2014and some sleepless ones. In some instances we were able to circumvent issues before they became problems, in others we had to work them through as they presented themselves, but in the end, the team came together to support one another and we were able to celebrate a successful launch.\u201d<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\" id=\"h-4-what-is-your-approach-to-coding-and-ensuring-your-code-is-solid-organized-and-optimized\"><strong>4.

Knowing the languages is one thing, but you want a candidate who lives, eats and breathes code. Part of this means your Back-End Software Engineer candidate should know how to manage their own code, recognize errors when they come up, know how to work through them, but they should also know best practices for maintaining their code.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-an-answer-you-d-hear-from-a-stand-out-candidate-2\"><strong><em>An Answer You\u2019d Hear From a Stand-out Candidate<\/em><\/strong><\/h3>\n\n\n\n<p>\u201cI spend most of my time writing code, as that\u2019s largely what\u2019s necessary for me to effectively fill the role of a Back-end Software Engineer, but I also spend time managing UI tests, optimizing and debugging as needed. I tend to rely on OOP to organize my code, however in the past I\u2019ve also used procedural programming to classify my code by action instead of object. But again, it comes down to what\u2019s most efficient and required based on whatever project I\u2019m working on. It also depends on what the team preference is, as I find some are particular about how it\u2019s organized. But on the whole, I\u2019m constantly testing and re-testing my code to ensure it meets the project\u2019s needs, and I work to maintain my skills outside of the office to ensure I\u2019m always up to date and working at peak capacity.\u201d<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\" id=\"h-5-what-are-some-of-the-best-practices-you-employ-during-the-development-lifecycle\"><strong>5.

But while certain aspects are flexible, others remain standard across the board\u2014and it\u2019s there that your Back-End Software Engineer candidate will show you their know-how and capability to handle the pressures associated with seeing a project through to completion by using the methodologies that are known to produce results. Bonus points if they can talk about specific processes that help them achieve goals and milestones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-an-answer-you-d-hear-from-a-stand-out-candidate-3\"><strong><em>An Answer You\u2019d Hear From a Stand-out Candidate<\/em><\/strong><\/h3>\n\n\n\n<p>\u201cOverall, the projects I\u2019ve worked on mostly follow the Agile approach, which is where my affinity for testing and retesting code comes from. However, I do have experience using the more progressional approach of the Waterfall method. I find that having experience in both makes it easier for me to transition between teams, particularly during the troubleshooting process, but I\u2019m happy to work in either methodology depending on what\u2019s required to complete the project. I also have experience working in unit testing and find it to be an important part of the process for finding logic errors and coding flaws. I also use multi-threading to improve application performance, rely on MVC to separate code, and use Hibernate for ORM frameworks.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prepping to interview a candidate for your Back-End Software Engineer position, but unsure of what questions to ask to ensure you\u2019re finding someone who can bring that \u201cextra something\u201d to your company?
