These exercises simulate real-world interactions, giving you a clearer picture of how they might integrate into your team.
Testing Team Compatibility with Real Scenarios
To get a better sense of how a candidate will perform in your team, create scenarios that reflect the challenges your mobile development team encounters. For instance, present a situation where the design team requests a feature that seems technically difficult to deliver within the timeline. Ask candidates how they’d approach discussing this with designers, project managers, and other stakeholders.
Look for candidates who stay calm under pressure and can adapt their strategies. Here’s an example of this mindset in action:
"In a project where our initial approach wasn’t working, I proposed pivoting to a new strategy based on emerging market trends. The team was hesitant at first, but we ultimately shifted gears and exceeded our project objectives."
Another effective strategy is pairing sessions, where candidates work alongside your developers on a small task. This hands-on approach not only tests their technical skills but also reveals how they collaborate in real time. Emily Flick, Senior Talent Acquisition Partner at MP: Wired for HR, underscores the importance of diverse teams:
"Teams that have a diverse group are more likely to succeed than those with the same personality types."
These practical evaluations naturally lead into discussions about company alignment.
Why Company Alignment Matters
Assessing company fit goes beyond individual tasks – it ensures a candidate’s long-term potential. Developers who align with your company’s values are more likely to thrive, especially in mobile development, where teamwork and user experience are key.
Shared values foster collaboration and creativity. As Greg Besner, Founder of Sunflow and CultureIQ, explains:
"Hiring for mission and value alignment is arguably the most important piece of the puzzle to get right."
Alignment also plays a big role in employee retention, which is critical for long-term success. A strong fit reduces turnover, saving time and resources. This is particularly important in mobile development, where losing a team member mid-project can disrupt workflows and delay progress.
To assess alignment, explore a candidate’s motivations and career goals. Cheryl Hyatt, Co-founder of Hyatt-Fennell Executive Search, shares:
"People do not only want a job as a way to make a paycheck; they want a job as a way to make a difference."
Ask about their past successes and failures, and how these experiences shaped their professional values. Look for signs they can adapt to your company’s communication style and decision-making processes.
With 94% of entrepreneurs and 88% of job seekers emphasizing the importance of a healthy workplace culture, it’s clear that fostering a positive environment benefits everyone. Emily Flick adds:
"Show enthusiasm about working with each unique individual on the team. At the end of the day, we all want someone who’s excited to work with us."
The goal isn’t to find someone who fits a rigid mold but to identify someone whose values and working style complement your team while bringing fresh ideas to tackle your mobile development challenges.
