Interview prep,
done differently
How Greenroom works, what we've learned building it, and honest advice for technical interviews.
Interview prep
Why Leetcode grinds don't prepare you for real technical interviews
Most interviewers aren't looking for optimal algorithms. They're evaluating how you reason through unfamiliar problems — and that's a completely different skill to train.
How it works
How Ari reads your GitHub to ask better questions
We pull your top repos, look at commit history, PR descriptions, and README context — then build questions around the decisions you actually made.
Voice interviews
Talking through code out loud is hard. Here's how to get better at it.
Speaking your reasoning in real time feels unnatural at first. These are the specific habits that make it click — and why practicing silently doesn't help.
Product
What Ari's feedback actually measures — and what it doesn't
Accuracy, depth, communication. A transparent look at the rubric Ari uses to evaluate your answers, and the things only a human interviewer can judge.
Career
Senior vs. staff: what actually changes in a technical interview
The questions aren't harder — the expected framing is. Senior engineers diagnose. Staff engineers zoom out. Here's how to shift the way you talk about your work.
Engineering
Building a voice interview AI: the latency problem nobody talks about
Getting Ari's response under 800ms took six months of infrastructure work. This is what we tried, what failed, and what finally made it feel like a real conversation.
