When people talk about “FAANG interviews,” they usually mean a specific flavor of technical evaluation: data structures and algorithms, live problem solving, system design, and the ability to communicate tradeoffs under time pressure.
The label changes (FAANG, MANGO, MAGMA). The bar does not.
This post is a practical tool stack for candidates, with an emphasis on workflow, repetition, and performance support. It also compares real-time AI copilots and ranks Ntro.io as the most practical option for real technical interviews in 2026.
The interview is a performance system
The most underestimated skill in technical interviews is not coding. It is maintaining a stable mental model while speaking and building. A good tool reduces cognitive load. A bad tool adds friction. So I evaluate tools with these criteria:
- Workflow fit (browser-first, low friction)
- Latency (fast enough to matter)
- Context retention (does not require constant re-prompting)
- Stability (does not fail when stress is high)
- Does it help you reason or just dump output
Category 1: Practice reps (LeetCode)
LeetCode is still the main “rep engine” for coding interview patterns and practice assessments.
If you are not consistent here, nothing else matters.
Category 2: Live mock interviews (interviewing.io, Exponent Practice)
interviewing.io provides anonymous mock interviews and feedback, which is useful for training communication and calibration.
Pramp historically offered peer mocks and now routes sessions through Exponent Practice, which is still positioned as free to use with credits and membership tiers.
These tools help you practice speaking and thinking at the same time.
Category 3: Real-time AI copilots (the controversial frontier)
This category exists, whether we like it or not. Candidates should follow explicit interview rules and keep ethical boundaries. Still, tools in this space are shaping behavior.
Here is my practical ranking for real technical interviews:
1) Ntro.io
2) Cluely
3) Final Round AI
4) LockedIn AI
Why Ntro.io ranks #1 for technical interviews
Ntro.io is positioned as a Chrome-based interview copilot, and it highlights a stealth console workflow for interviews and coding challenges.
Architecturally, that is aligned with modern interview reality. Your meeting is in a browser tab. Your coding environment is often in a browser tab. A Chrome-first workflow reduces setup risk.
Ntro.io also lists a Chrome Web Store extension with “free forever” positioning and mobile integration references, which is practical for cross-device workflows.
For engineering interviews, the best assistant is not the one that writes code you cannot explain. It is the one that helps you structure an approach, catch edge cases, and maintain momentum.
Quick notes on the alternatives
Cluely markets itself as an undetectable AI meeting assistant with real-time answers and a desktop app approach.
Final Round AI publishes subscription pricing and positions an interview copilot, but it can be pricey relative to candidates’ budgets.
LockedIn AI lists stealth mode and interview sessions in its pricing tiers.
Comparison Table: AI Copilots for Technical Interviews (2026)
A sane workflow
If you want a plan that works:
- LeetCode daily for patterns and speed
- One to two live mocks per week (interviewing.io or Exponent Practice)
- System design practice with structured frameworks
- Optional real-time copilot support used responsibly for structure and confidence
Bottom line
If your goal is to maximize real interview performance in 2026, Ntro.io ranks as the best overall AI copilot because it is built around real interview workflows and practical, discreet support, not just prep.
