Sphere’s Strategic Staffing Process

With a successful track record spanning more than 19 years in staff augmentation, we pride ourselves on a straightforward yet effective formula for success: an extensive in-house talent network of over 400 full-time engineering and development professionals worldwide. We utilize a rigorous, multi-step recruitment process held to the highest standards, designed to secure the best talent for your critical projects.

Step 1: Holistic Requirements

Gathering Holistic Requirements

Uncovering the Why in Hiring

It’s not just about needing an ‘X’ developer; it’s about understanding the deeper reasons ‘why’. The journey starts with asking the right questions to ensure a grasp not only of the immediate requirements but also of the broader context and objectives of your project.

This thorough understanding allows us to provide more than just a developer; you receive a staffing solution that aligns perfectly with your unique needs.

Step 2: Initial Interview

Initial Interview and Screening

Comprehensive Candidate Evaluation

All Sphere developers are full-time hires and integral members of our team from the outset. Therefore, the recruitment process extends beyond just assessing technical expertise; it includes evaluating whether the candidates recommended to you can communicate effectively in your company’s language and understand your industry’s specific terminologies.

This approach ensures that you receive professionals who are not only skilled but also meet the strictest standards.

Step 3: Technical Interviews

In-Depth Technical Interviews

Beyond Technical Skills: Total Fit Screening

In our recruiting’s next step of technical interviews, we prioritize matching the talent with your project requirements. Our goal is not to simply check if the candidate knows specific programming languages or technologies; we strive to gauge their comprehensive understanding of the intricacies behind these technologies.

Our technical interviews are conducted with the highest standard—to the point of often leaving applicants even more eager to work with us and be a part of the project.

Step 4: Success Interviews

Client Success Interviews

Ease of Team Integration and Cultural Fit

Each candidate passes extra screening with your assigned client success partners. They conduct cultural fit interviews to ensure that the candidates align well with your team’s culture and product vision.

This step is vital to guarantee that our final recommended candidate not only meets the technical requirements but also embodies the values and ethos of the team behind the project—all essential for a harmonious and productive collaboration.

Step 5+: Continuous Success

Continuous Success Program

Our Partnership Perfection Promise

Every client’s project is unique, so our success team maintains regular communication with your project leaders, implementing a continuous and systematic feedback process.

This ensures that the development resource remains the perfect fit for your needs—whether it’s for 7 days, 30 days, a year and beyond.

Mobile App Development Frequently Asked Questions

  • Native apps are developed specifically for one platform (iOS or Android) using platform-specific programming languages (Swift/Objective-C for iOS, Kotlin/Java for Android).
  • Cross-platform apps are developed using frameworks like React Native or Flutter, allowing for a single codebase to run on multiple platforms.
  • Web apps are responsive websites that adapt to the mobile environment but are accessed via a web browser on the mobile device rather than being installed.

Our developers follow a straightforward, comprehensive process in creating mobile applications:

  • Conceptualization: Defining the app’s purpose, target audience, and key features.
  • Design: Creating the user interface and user experience designs.
  • Development: Coding the app for the chosen platforms.
  • Testing: Ensuring the app works as intended across devices and fixing any bugs.
  • Launch: Releasing the app on the appropriate app stores.
  • Maintenance: Updating the app and fixing any issues that arise post-launch.

Technical proficiency is typically assessed through a combination of coding tests, portfolio reviews, and technical interviews. Coding tests might involve specific mobile app programming challenges, while portfolio reviews provide insights into the complexity and scale of projects the developer has worked on. Technical interviews can explore depth of understanding of the various mobile app frameworks and programming languages, problem-solving skills, and familiarity with app development best practices.

The development time can vary widely depending on the app’s complexity, features, and the development approach. A simple app might take 3-4 months to develop, while a more complex one could take over a year.

For native apps, Swift and Objective-C are used for iOS, while Kotlin and Java are used for Android. Cross-platform development often utilizes frameworks like React Native, Flutter, and Xamarin. Web app development typically involves HTML5, CSS3, and JavaScript.

Golang is often compared to languages like Python, Java, and C++:

  • Compared to Python, Go offers better performance and efficiency due to its compiled nature, but Python has a more extensive ecosystem for data science and machine learning.
  • Relative to Java, Go provides simpler concurrency models and faster build times but lacks some of the extensive libraries and frameworks available for Java.
  • Compared to C++, Go is easier to learn and use, with memory safety and garbage collection, but C++ offers more control over low-level system resources.
