Describe the role. RoundZero handles the rest. No ATS setup, no keyword filters, no manual screening.
The hiring funnel still starts with résumés — a weak signal that's easy to game. Years of experience is a proxy, not a measurement. Great engineers can look average on paper, and weak candidates can fabricate their way past ATS filters. RoundZero cuts through the noise. It evaluates how candidates actually think, not what they claim in a document. What follows is how that works.
Describe the role. RoundZero handles the rest. No ATS setup, no keyword filters, no manual screening.
Applicants submit and go — RoundZero takes over. Pre-evaluation runs immediately. Zero handles salary, relocation, visa, and other screening so your team doesn't have to.
Strong candidates are interviewed by Zero, then you get ranked reports with scores, strengths, and evidence. You're notified the moment they're ready.
Review only the top-ranked candidates. Every score links to real conversation — no more guessing.
“It noticed I’d been vague about Redis Streams and asked me to draw out exactly how messages were ordered. It felt less like a quiz and more like a conversation with a senior engineer who had already read my résumé.”
— Sarah Chen, Senior Backend Engineer
You mentioned building a real-time notification system. Walk me through the architecture decisions.
Pub/sub with Redis Streams for brokering. The tradeoff was latency vs. ordering — we chose at-least-once with client-side dedup.
How did dedup hold up at scale? Specifically, what happened on a client reconnect after going offline for several minutes?
We kept a sliding window of message IDs in IndexedDB. On reconnect we replayed missed entries and dropped duplicates against the window.
Voice communication is assessed after the text interview and blended into the final communication score (60% voice, 40% text).
Each candidate comes with a structured report covering reasoning, communication, and relevant experience — with an overall score, key strengths and concerns, and role-specific evaluation.
System design, distributed tradeoffs
Concise, structured under pressure
Validated against four prior roles
After RoundZero, you don’t see applicants — you see ranked candidates.
Candidates are ordered by actual evaluation, not keyword matches or resume quality. Every recommendation links back to real responses and reasoning.
