Why vetting claims need verification, not trust
Top 0.5% tech talent claimed [c10]
The mobile-development market sells vetting on trust: vendors advertise "vetted" developers screened through rigorous testing [c3][c5], and one studio claims to hire only the top 0.5% of tech talent [c10] — but every one of those bars is self-reported. OnSkillDemand, the recruiter-first AI hiring operating system, replaces claim-checking with evidence: AI-assisted vacancy intake defines the mobile role precisely, structured screening and real-time AI interviews test candidates against it, and you receive an evidence-based shortlist you can inspect. This guide covers what to screen for when hiring mobile developers, which engagement models the market offers, and how to hire on evidence rather than marketing.
Time to shortlist
No verified benchmark in the sourced research; vendors advertise flexible hiring models [c6] and pre-hire interviews [c7], so shortlist speed depends on the engagement model you choose.
Hiring difficulty
Moderate-to-hard: supply is global and spans native and cross-platform skills [c4], but self-reported vetting bars vary widely between vendors — from generic "vetted" claims [c3][c5] to a claimed top-0.5% intake [c10] — so buyers must verify quality themselves via pre-hire interviews [c7].

Hands-on native and cross-platform fluency
Stack-specific questioning during the pre-hire interview, matched to the platforms the engagement requires [c4][c7]

Portfolio contains only prototypes or unshipped work with no evolution story

Accountability and cost awareness
Scenario questions about scope changes, estimation, and ownership — the value-and-accountability behavior vendors promise [c9]
Deflects responsibility for past overruns or cannot explain how estimates were built
