How to Identify Low‑Quality Resumes and Spot Fake Candidates in Technical Interviews

The author reflects on the rapid expansion of the internet industry, noting the surge of IT workers and the oversupply of Java and iOS engineers since 2016, which makes resume screening a critical challenge for hiring teams.

Key red flags in initial resume screening include candidates with unusually high degrees for their age, senior candidates lacking real technical experience, project listings that consist mainly of generic CRM, e‑commerce, or management systems, and projects whose timelines do not match market realities (e.g., lottery or live‑streaming projects launched before regulations allowed them).

Other warning signs are repetitive technical architectures across multiple jobs, over‑emphasis on cutting‑edge technologies while ignoring mature solutions, and candidates whose work history shows frequent cross‑city moves without verifiable company backgrounds.

During the interview stage, the author recommends probing company and team size, role distribution, product launch dates, user counts, concurrency metrics, and detailed project timelines to verify the authenticity of the resume.

Specific technical depth questions are suggested, such as asking a self‑declared Redis expert to describe used data structures, serialization methods, and real‑world issues; or testing an HTTP‑savvy candidate on header usage, request‑response flow, chunked transfer encoding, and cookie handling.

The article concludes that while some resume embellishment is inevitable, interviewers should strive for a balanced assessment that filters out exaggerated claims while still recognizing genuine talent, ultimately helping teams recruit suitable IT partners.
