AI Interview Readiness Checklist
Everything you must verify before taking an AI interview on Mercor or micro1. Print this sheet or check items off digitally before starting your real screening.
Day-Of Interview Checklist (7 Final Verification Steps)
Complete these 7 checks immediately before launching your live AI interview on Mercor or micro1:
1. Stable internet, laptop plugged in
Connect to reliable high-speed Wi-Fi or ethernet and keep charger connected so your device doesn't enter power-saver throttling mid-interview.
2. Quiet room, good light on your face
Ensure zero background chatter and face a window or front desk lamp so the interviewer can see you clearly.
3. One browser tab. Close overlays and extensions like Grammarly or Loom
Close secondary tabs, Discord, Slack, Grammarly, and Loom to prevent background popups or anti-cheat screen flag triggers.
4. Camera at eye level, eyes on the camera
Elevate laptop on a stand or books so your eye contact is locked directly onto the camera lens rather than looking down at screen corners.
5. Resume open and reviewed beforehand, closed during the interview
Review your project dates and technical metrics prior to launch, then close all files to maintain 100% natural conversational presence.
6. Your 5 stories reviewed, plus the 3 numbers you'll mention
Have your core technical situation-action scenarios and 3 quantified impact metrics (e.g. 35% speedup, 500+ weekly jobs) top-of-mind.
7. Bridge phrase ready for when you need a moment to think
Keep a professional bridge phrase ready ("Let me walk you through that," "There are two parts to how I architected this") instead of leaving dead silence.
Pre-Apply Checklist: 4 Costly Mistakes to Avoid Before Submitting
These are the top avoidable disqualifications candidates report in applicant forums. Verify each item before clicking apply:
1. Match Profile Availability to the Roleβs Requirements (Only If You Can Commit)
Check the schedule and hours listed on the role card before applying. If a role specifies 20 hrs/wk, setting your profile to 10 hours can filter your application out of consideration. Align your profile availability with the role's required hours, but only if you can actually commit to working them once placed.
Application Strategy • Avoid availability mismatches
2. Apply Early & Complete 100% of Profile in One Sitting
Partially filled profiles get deprioritized in hiring manager reviews (HMR). Complete all portfolio links, resume parsing, and baseline questions in your first session.

3. Start Tasks Promptly Once Placed on a Project
When matched to a project wave, claim and submit your initial task right away. Accounts with 0 tasks completed risk having their seat reassigned to standby evaluators.

4. Confirm Country Eligibility & Deel Tax Status
Check whether the role requires US residency (W-9) or accepts International contractors (W-8BEN). Both platforms disburse earnings via Deel; verify your documents early.

Wired Headset / Earphones with Dedicated Microphone
Built-in laptop microphones pick up room echo and keyboard clicks, confusing automated speech-to-text parsers. Use wired headphones with a mic.

High-Speed, Stable Internet (Minimum 15 Mbps Download / 5 Mbps Upload)
Close streaming apps, VPNs, downloads, and heavy background tabs before starting to prevent video stutter or audio drops.

2. Physical Space & Lighting
Front-Facing Light Source (No Backlighting)
Position light or a window directly in front of your face. Windows behind you cast you in shadow and trigger automated lighting warnings.

Quiet, Closed Room with Zero Distractions
Notify household members and close windows. AI screeners penalize background human voices as potential collaboration or cheating.
Source: Mercor Honor Code & Proctoring Rules
20 Uninterrupted Minutes Scheduled
Mute phone, silence computer Slack/Discord notifications, and close secondary communication windows.

3. Platform Rules & Retake Policies

micro1: Target One Core Skill & Use Zara Prep
On micro1, specialize your profile in one primary tech stack or evaluation domain. Use the micro1 prep tool to familiarize yourself with Zara's evaluation rubrics.

4. Answer Structure & Pacing Formula
Target Answer Duration: 60 to 90 Seconds
Responses under 30 seconds lack sufficient keyword signals for the transcription scorer. Responses over 2 minutes risk rambling. Aim for 70β120 words per question.

Strict STAR Framework: Situation, Task, Action, Result
State the challenge (10s), your assigned task (10s), the exact actions you owned (30s), and end with a quantified, measurable outcome (15s).

Prepare 3 Quantified Stories From Your Resume
Have numbers ready: % reduction in latency, dollars saved, patient volumes handled, or accuracy benchmarks achieved. AI screeners weight concrete metrics heavily.

Look at the Camera Lens, Do Not Read From a Hidden Script
Eye-tracking algorithms flag candidates reading pre-written notes on secondary screens. Natural pauses and eye contact with the webcam build credibility.
