TECHNICAL ROLESHACKERRANK01 Linking Key Technical Roles Understanding how technical roles differ (and how they’re similar) is one surefire way toensure a good fit. Not only will it help you better understand each respective role, but howeach of them work within the rest of the team––a must-know when screening for team fit.The Technical EcosystemThe technical roles outlined in this guide fall under two broad teams: the data team, andthe software development team. Both have different, but equally important roles in drivingthe organization forward. You can see this illustrated in the example to the left, whichshows how technical teams operate within a SaaS company.It’s worth noting that there’s no one-size-fits-all model for how these teams function in anorganization; every case is unique. To truly understand how your technical teams function,it’s best to sync up with your hiring manager.Technical Org Chart Example: SaaS modelWith this context in mind, we’ll move on to how to assess each team.Prospects& Customersgives feedbackfrom the field todrives productadoption forSales, Marketing,& Customer Servicerelays feedbackfrom the field torelays finishedproduct toData TeamSoftwareDevelopmentTeaminforms decisions requests insights fromDataScientistinformsroadmap ofDataEngineerBack-EndDevelopersharesproduct withFull-StackDeveloperinforms decisions ofrelays refined roadmap toDevOpsProductrequests insights fromw w w.hackerrank.comdevelops software forP.07

SOFTWARE DEVELOPMENT ROLESHACKERRANK03 Assessing SoftwareDevelopment Roles Though, as a whole, they have a unified goal, a software development team consistsof an eclectic set of specialists, all with their own areas of expertise. More than any othertechnical team, software development teams must constantly be in sync; they’re constantlybuilding on one another’s work to make headway toward a final product. In this category,finding personally and professionally compatible hires is mission critical.DevOpsBuilds & maintainsinfrastructure requiredfor the project to workHere’s how each role contributes to an organization:Development Roles Front-End Developer: The liaison between the technical and non-technical worldFront-End DeveloperBack-End Developerof any organization. They work between the back-end developers and non-technicalExecutes client-side code:makes the projectusable and accessibleExecutes server-side code:builds the foundationof the projectstakeholders in design and product to create the client-facing. Back-End Developer: The architect that builds the base the front-end developer buildson. Tasked with writing server-side code, they’re often utilized to build APIs, and areserverespecially core in facilitating scalable designs. Full-Stack Developer: The generalist that’s capable of working on both the front-endand the back-end. They often have a wide pool of skills and knowledge, but specializein a select few technologies. Often, you’ll find they’re slightly more front-end oriented,user devicesdatabaseor slightly more back-end oriented (rarely both). Note: There’s some disagreement overhow to define “full-stack” in this context. For the full backstory, check out this post.Support Roles DevOps Specialist: They use knowledge of QA, software development, and operationsto help make the software development software as smooth and efficient as possible.They make sure the work the team builds is sustainable in the long run – both from atechnical standpoint, and from an operational one.w w w.hackerrank.comP.17
QUICK TIPHACKERRANKAssessing Junior vs. Senior DevelopersBoth Junior and Senior Developers can hold virtually any specialized development role—but their contributions won’t always be the same. While Senior Developers are generally more seasonedand independent, Junior Developers may need more guidance to do their best work. Make sure you clarify the level of seniority you expect from each candidate in addition to the specialized skills you’re seeking.Here’s what you can expect from each respective seniority level:Junior Developer: This level of developer is newer to the space, with limited experience, butSenior Developer: This level of developer is more seasoned, with a solid technical expertisea good technical foundation.
