Collaboration skills are vital for working in cross-functional teams. The best developers can simplify complex technical concepts for non-technical stakeholders and thrive in agile environments. Research shows 70% of high-performing teams prioritize open knowledge sharing, and 65% of employers value experience with frameworks like Truffle, Hardhat, or Ganache.
Compliance awareness is especially critical in regulated industries like healthcare and finance. Developers should be familiar with standards such as HIPAA, GDPR, and FDA guidelines. They should also have hands-on experience with data encryption, authentication, and secure API communication. Healthcare data breaches are particularly costly, averaging $10.93 million per incident, with 276.8 million healthcare records compromised in 2024 alone.
Candidates must also understand the balance between security and usability. As Thisisglance.com aptly states:
"Security isn’t something you buy, it’s something you design, implement and maintain."
Assess their knowledge of secure data storage, backup, and removal practices, as well as their familiarity with Business Associate Agreements when dealing with third-party vendors. Awareness of key principles like data minimization, purpose limitation, and user consent is equally important.
A strong quality assurance mindset is another must-have. Developers should demonstrate expertise in unit testing and scenario-based troubleshooting. This is critical, as most security breaches stem from design flaws. Surveys indicate that 90% of organizations consider compliance knowledge a key requirement for developers.
The mobile development field is evolving quickly, with projections estimating over 600,000 medical apps by the end of 2025, growing at a CAGR of 11.6%. Your ideal candidate should exhibit a growth mindset and adaptability, showcasing lessons learned and outcomes achieved in their previous roles.
1. Describe a mobile app you’ve developed and the challenges you faced
This question is designed to uncover hands-on experience, problem-solving skills, and the ability to communicate technical concepts clearly. Pay close attention to examples that involve custom native techniques or advanced integrations, as these often separate candidates with practical expertise from those with primarily academic knowledge.

How did they address device compatibility issues? Advanced integrations like AI, AR, or VR are particularly worth noting, as they can significantly influence performance, compatibility, and the overall user experience.
Security is another critical area to explore. Candidates should provide details about implementing data encryption, using secure APIs, and ensuring compliance with relevant regulations. Performance optimization is equally vital – users expect apps to run quickly and smoothly. Ask about any performance bottlenecks they encountered, how they resolved them, and the metrics they used to measure success.
Mobile app development often requires collaboration with UX/UI designers, researchers, and project managers. Strong answers will highlight how candidates maintained clear communication, coordinated effectively with team members, and met deadlines.
Be cautious of vague responses or a lack of detail about decision-making and testing processes. The strongest candidates will not only demonstrate technical skills but also explain how market research, responsive design, and solid project management contributed to their app’s success.
2. What factors influence your choice of native vs. cross-platform development?
This question sheds light on whether candidates grasp the strategic impact of their technical decisions. Strong responses will demonstrate an understanding of factors like performance, budget constraints, and team expertise. Look for candidates who can outline specific scenarios where one approach might be more suitable than the other.
When it comes to performance, seasoned developers often emphasize the advantages of native apps. Built using languages like Swift, Objective-C, Java, or Kotlin, native apps have direct access to device resources, leading to faster and more responsive experiences. On the other hand, cross-platform frameworks, while convenient, introduce an abstraction layer that can affect performance. However, modern tools like Flutter have made significant strides in minimizing this performance gap.
From a cost perspective, cross-platform development can lower expenses by as much as 30%, thanks to the ability to reuse code across platforms. That said, this cost efficiency may come with some trade-offs.
"Native apps tend to perform better because they’re designed specifically for each platform. Cross-platform apps are slower since they run on both iOS and Android from the same codebase, but they’re quicker to build and maintain." – Annetta, App Developer
Team expertise is another critical consideration. If your developers are already proficient in JavaScript, frameworks like React Native can enable faster project delivery. Conversely, introducing unfamiliar tools can slow down timelines and complicate workflows. Additionally, hiring for niche technologies, such as Kotlin Multiplatform, can be more challenging due to a smaller talent pool.
Security is another area where native development often shines. Native apps can more easily leverage platform-specific libraries for features like file encryption and fraud detection. Cross-platform apps, in contrast, may face delays in implementing security updates, which can be a dealbreaker for applications handling sensitive data.
Finally, access to native features is a deciding factor. Native development allows immediate use of new iOS and Android functionalities, while cross-platform solutions may lag behind, requiring either framework updates or custom native code to bridge the gap.
The best candidates will acknowledge these trade-offs and show how their choices align with business goals, team strengths, and project needs. Be cautious of candidates who rigidly favor one approach without considering the broader context, as this could signal a lack of flexibility or strategic thinking.
3. How do you approach integrating third-party APIs into a mobile app?
This question tests a candidate’s technical skills in API integration while gauging their understanding of security, authentication, error handling, and data validation.
A strong candidate will outline a clear, systematic approach that emphasizes security from the beginning. For instance, they might highlight the importance of using HTTPS to encrypt data transmissions and implementing OAuth 2.0 for controlled API access while protecting sensitive information. Additionally, they should point out that mobile apps benefit from using system browsers for user logins instead of embedded web views. This approach not only enhances privacy but also enables Single Sign-On (SSO).
Another key security practice is using PKCE (Proof Key for Code Exchange) to safeguard authorization responses. Candidates should also demonstrate knowledge of secure token management, such as issuing opaque tokens for access and refresh tokens, ensuring they remain confidential and unreadable. Once security measures are in place, attention shifts to error management.
With 85% of apps vulnerable to input handling issues, candidates should stress the importance of robust validation on both the client and server sides. They might discuss strategies like retry logic, circuit breakers, and exponential back-off mechanisms to handle network issues effectively. Given that 30% of security breaches are linked to poor input handling, middleware can be used to standardize error responses and reduce vulnerabilities.
Real-world experience also plays a crucial role in API integration. For instance, integrating social logins (e.g., Facebook or Google) often involves challenges like token expiration, permission denial, or SDK incompatibilities across operating systems. A well-prepared developer will address these issues by maintaining test matrices for various OS versions and devices, offering fallback authentication methods, and combining SDK token management with backend validation.
Monitoring and managing API usage is another vital aspect. Candidates should demonstrate familiarity with techniques like rate limiting to prevent abuse, correlation IDs to trace requests, and feature flags to disable problematic features temporarily during errors.
Lastly, candidates should reference secure token management practices and stay updated on evolving standards, such as OAuth 2.1, which improves upon OAuth 2.0 by making PKCE mandatory and phasing out less secure flows.
Responses that neglect error handling, security practices, or real-world challenges indicate a lack of readiness for the practical demands of mobile app development. A comprehensive approach that combines technical expertise with real-world insights is essential for tackling today’s integration complexities.
