Practice how you
sound in interviews

Aria listens to your answers and scores you on four dimensions — structure, completeness, clarity, conciseness. Real numbers. Every answer. No vague encouragement.

How it works

A pressure practice loop.

Interviews are spoken. Pressure breaks sequencing, completeness, and clarity. Aria gives you a repeatable loop: answer out loud → scorecard → one fix → retry.

The scorecard

Four scores.
Zero vagueness.

Interviewers evaluate you on more than facts. Aria measures the exact dimensions they care about — so you know precisely what slipped, not just that something did.

Completeness 6.1 → Aria tells you the exact point you dropped. Not "be more thorough."

What improvement actually looks like.

Same question. One retry. One fix: replace buzzwords with specifics. Toggle and listen.

A microservice is basically when you split your application into smaller parts… I would choose microservices because it's more modern and scalable. Big companies like Netflix use them, so it's usually better.
A microservice is an independently deployable service with its own database and API. I'd choose it when you need independent scaling — if payment processing needs 10x more resources, you scale just that service.

Fix: Drop the buzzwords. Define it precisely, then give a concrete scenario where you'd choose it.
Pattern learned: Precise definition → concrete scenario → specific benefit. That's what interviewers remember.

Why it works

Not a chatbot. A practice loop.

You've tried ChatGPT, mock interviews, articles. Here's what's different.

Aria live waveform recording interface
Voice practice

Talk out loud.
Aria is listening.

Most interview prep is silent. You read a model answer and think you understand. Real interviews don't work that way. Aria makes you say it — out loud, on the spot.

  • Questions matched to your target role and seniority
  • Live waveform so you see yourself thinking in real time
  • Transcript reviewed alongside your verbal delivery
Aria structured feedback breakdown
Structured feedback

Not "be more confident."
Specific gaps. Specific fixes.

Aria doesn't encourage. It analyses. Every answer gets a breakdown of what landed and what didn't — with exact examples from your own response.

  • What worked and what to fix, in bullet points
  • Direct quotes from your answer showing where clarity broke
  • One retry prompt after every scored answer
Aria cross-session pattern tracking
Pattern detection

The thing you keep doing.
Now visible.

Single-session feedback only goes so far. Aria tracks patterns across all your sessions and surfaces recurring weaknesses you've stopped noticing yourself.

  • Cross-session patterns from session 2 onwards
  • Named habits: "You consistently drop the result in STAR answers"
  • Future questions targeted at your weakest dimension
From the founder

Why I built Aria.

I kept seeing strong engineers lose offers for a reason that's hard to measure: their answers collapsed under pressure. Aria is a practice loop for spoken clarity — not more memorization.

Transcript: I'm a software engineer, and I kept seeing strong engineers lose offers for a reason that's hard to measure. Their answers collapsed under pressure. In casual conversations, they could explain complex systems clearly. In interviews, the same answers became vague, unstructured, missing the impact. So I built Aria as a simple practice loop for spoken clarity. You answer one real interview question out loud — about 60 to 90 seconds. Aria scores your delivery on four dimensions: Structure, Completeness, Clarity, Conciseness. Then it gives you what to fix. You retry once — and you see the score move. We only process audio while you're recording. It's transcribed, scored, and the raw audio is deleted. If you want to see how your delivery holds under pressure — try one question. It takes about five minutes.

What I liked about Aria compared to ChatGPT is that it was less of a "yes-man" — it didn't try to compliment or understand me. I really enjoyed the score. I wanted to get it up. That's what kept me going.

FAQ

Common questions

Human mock interviewers give subjective feedback that varies wildly. Aria gives you the same four scores every time, making progress measurable. You can practice at 11pm, retry the same question five times, and never feel embarrassed. The feedback is more structured and often more honest than what a friend or recruiter would say.
Both. Aria handles behavioral (STAR format, leadership, conflict resolution), technical system design, and role-specific questions. The four-dimension scoring applies equally — a behavioral answer can be just as unclear and incomplete as a technical one.
Yes. Tell Aria your target role, company, and seniority level. Questions are tailored to match the style and depth you'll face — entry-level FAANG behavioral rounds feel different from Staff-level system design, and Aria adjusts.
Aria uses your microphone to record your spoken answer. Speech is transcribed in real time, then Aria evaluates the content and structure of what you actually said. You hear a spoken response from Aria and see a written scorecard. Raw audio is deleted immediately after transcription — we don't store recordings.
Yes — cancel from account settings any time. You keep access until the end of the billing period. No fees, no "are you sure?" emails, no dark patterns.
