Is this actually like a real interview?

Yes. Ari probes your specific answers, asks for concrete metrics, pushes back when claims are vague, and manages the 15-minute clock exactly like a calibrated bar-raiser at a tier-1 company.

Does my target company or employer see my score?

No. PreHire.tech is exclusively candidate-facing. Your practice sessions, audio recordings, and evaluation reports are private to you. We never share or sell your data to hiring organizations or ATS systems.

What if my target company or role isn't in your pre-built library?

Simply paste the job description into our setup wizard. PreHire extracts the 4 to 5 core competencies and builds a tailored rubric with 1/3/5 scoring anchors that you can inspect and refine before entering the session.

Is my voice recording stored, and can I delete it?

You maintain total sovereignty over your data. In your settings, you can permanently delete audio recordings and transcripts with a single click at any time.

Evaluated Competencies & 1 / 3 / 5 Scoring Anchors

PreHire avoids vague ratings. Each competency is scored strictly against concrete behavioral evidence from your transcript.

Customer Obsession & Ownership

Rubric Weight:35%

Working backwards from real customer pain, taking long-term responsibility beyond one's immediate code repository.

Scoring Rubric Anchors

Level 1 — Below Bar

Says 'that's not my job' or prioritizes technical novelty over customer value.

Level 3 — Meets Bar

Solves customer pain points directly, takes responsibility for post-launch bugs, and writes thorough runbooks.

Level 5 — Exceptional

Identifies systemic customer pain before it's reported; advocates fiercely for end-user safety even when it complicates immediate deliverables.

Sample Interviewer Probes (Ari)

“Tell me about a time you made a decision that cost the team engineering time in the short term to protect the customer in the long term.”

Dive Deep & Root Cause Analysis (5 Whys)

Rubric Weight:30%

Drilling down to the foundational cause of performance anomalies, memory leaks, or recurring operational tickets.

Scoring Rubric Anchors

Level 1 — Below Bar

Applies superficial patches without understanding root causes; dismisses intermittent bugs.

Level 3 — Meets Bar

Uses the 5 Whys technique, examines heap dumps and telemetry logs, and implements preventative tests.

Level 5 — Exceptional

Relentlessly pursues elusive race conditions; invents novel diagnostic tooling that eliminates entire classes of operational defects.

Sample Interviewer Probes (Ari)

“Describe a complex, intermittent bug in production that stumped the team for days. How did you isolate and resolve the root cause?”

Bias for Action vs Calculated Risk

Rubric Weight:20%

Making high-velocity two-way door decisions with 70% information while protecting one-way door architectural commitments.

Scoring Rubric Anchors

Level 1 — Below Bar

Suffers from analysis paralysis or recklessly rushes irreversible database schema changes without backup plans.

Level 3 — Meets Bar

Distinguishes between reversible (two-way door) and irreversible (one-way door) decisions; moves quickly on the former.

Level 5 — Exceptional

Decisively breaks logjams when data is ambiguous; creates rapid proof-of-concepts that de-risk major initiatives in days rather than months.

Sample Interviewer Probes (Ari)

“Tell me about a time you had to make a critical technical call with incomplete requirements. What was the outcome?”

Scalable Distributed Design

Rubric Weight:15%

Designing decoupled, asynchronous AWS microservices that scale horizontally without hot partitions.

Scoring Rubric Anchors

Level 1 — Below Bar

Designs monolithic components with single points of failure and unpartitioned relational tables.

Level 3 — Meets Bar

Applies SQS/SNS decoupling, DynamoDB partition key best practices, and stateless autoscaling.

Level 5 — Exceptional

Masterfully manages shard key skew, backpressure throttling, and circuit breakers across high-throughput serverless architectures.

Sample Interviewer Probes (Ari)

“How would you design an event processing queue that absorbs massive Prime Day traffic spikes without starving lower-priority events?”
