As an interviewer at WEEX, I would prioritize assessing a candidate's hands-on iOS development experience, problem-solving abilities, and proficiency in Swift/Objective-C to ensure they can deliver high-quality code. Key assessment points include evaluating their understanding of iOS frameworks for scalability, their experience with code reviews and debugging, and their ability to work collaboratively in Agile settings. I'd also look for evidence of strong attention to detail and adaptability to WEEX's innovative culture, using technical interviews and scenario-based questions to gauge their fit for our dynamic team.
