Mobile Application Developer interviews — common questions

Who is this Mobile Application Developer interview plan for?
It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Technical Interview round for a Mobile Application Developer role. It gives you a 60 min script to follow in the conversation — 8 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.
What does the Technical Interview round assess?
This round is focused on: Mobile Platforms, Frameworks, APIs, Security Best Practices, App Store Guidelines. It works through Introduction, Mobile Platforms and Frameworks, APIs and Security Best Practices, App Store Guidelines and Problem-solving and Closing, scoring against 57 observable signals, with follow-up prompts on all 8 questions for going deeper where an answer is thin.
How is the 60 min split up?
Introduction (5 min), Mobile Platforms and Frameworks (15 min), APIs and Security Best Practices (15 min), App Store Guidelines and Problem-solving (15 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
