> **In short** Engineering teams have more applicants than interview hours. **Tracy AI Interviewer** runs the first technical conversation for every software engineer: questions on their own stack, a coding task and follow-ups on approach and trade-offs.
>
> A recording, timestamped transcript and assessment per question let an engineer decide from the candidate's own words.
>
> A Tracy customer cut its average time to hire from 44 days to 7.
>
> Engineers keep system design, team fit and the offer. Next: create an interview for one role.

We make Tracy AI Interviewer.

Engineering teams get more applicants than they have engineers to interview them. The usual compromise is a take-home or a timed test, which shows an output and hides the thinking, followed by a phone screen that takes engineer time. An AI interview for software engineers moves the conversation to the start. Every applicant is interviewed on their own stack, asked to solve a problem and asked why.

Tracy AI Interviewer does that. She asks questions in the candidate's own field, follows up on their approach and trade-offs and waits for the end of the thought. Your engineers read a recording, a timestamped transcript and a written assessment per question, and spend their hours on the people worth meeting. Our guide to [AI technical interviews](/blog/ai-technical-interviews) covers the format in general.

**Use Tracy for the first technical round when:**

- applicants outnumber the engineers who can interview them;
- you hire for the same role again and again;
- you want each candidate asked about their own stack, not a shared quiz.

**Keep a person for** the system-design round, the team-fit conversation and the offer.

## What does an AI interview for software engineers cover?

Describe the role and Tracy drafts the questions from the job description, or bring your own. Each item below is a setting on the role, as the [product page](/product) shows.

- **Your stack and your skills.** You set the skills the role must show, such as backend design, databases or debugging, and the weight each one carries, per role or for a family of roles.
- **Style.** Interview style runs from quick to deep and from technical to behavioural.
- **A coding task inside the interview.** Live coding, SQL, debugging or multiple choice, followed by questions on approach and trade-offs.
- **CV check, if you turn it on.** Tracy can read the CV and ask about what it claims, so a listed system becomes a question about that system.
- **A spoken-language check,** when spoken communication matters for the role. It evaluates fluency, coherence, grammar, pronunciation and vocabulary on a 0 to 100 scale beside the transcript.

For a bank of questions to start from, see [software engineer interview questions](/blog/software-engineer-interview-questions).

## What do follow-ups find that a test does not?

A test scores what a candidate produced. A follow-up asks about the part they did not write down.

| Opening question | Follow-up | What it shows |
| --- | --- | --- |
| Your endpoint is slow after a release. Where do you look first? | The query plan looks the same as before. What next? | Whether they have a method or a list of guesses. |
| Your cache returns stale data after a write. How do you fix it? | Two services write at once and an invalidation arrives late. What does a reader see? | Whether they understand the trade-off behind the fix. |
| Walk me through how you would split this service in two. | Which half would you be sorry to own at 3 a.m., and why? | Operating experience as well as design. |
| You chose a hash map here. What would make you pick a sorted array? | How does that change if the input does not fit in memory? | Judgement about approach, tested in the coding task. |
| Tell me about a bug you shipped. | What did you change in how you review after that? | Whether they learned something and can say what. |

The first answer is the one a candidate prepared. The follow-up depends on what the candidate said, which is why a fixed form cannot ask it.

## A worked example: a coding task and the follow-up

This is an illustration with sample data, not a real interview. The candidate is fictional. In this illustration, Tracy sets two tasks and asks the candidate to talk through their approach, then turns to a design question.

> **Tracy:** Your cache returns stale data after a write. How do you fix it?
>
> **Candidate (fictional):** Invalidate the key on write, with a short expiry as a backstop.
>
> **Tracy:** Two services write at once and an invalidation arrives late. What does a reader see?
>
> **Candidate:** Stale data until the expiry. I would version the keys so a late invalidation cannot remove a newer value.

A sample excerpt of the written assessment, written by us:

| Question | Assessment (sample) |
| --- | --- |
| Task 1, merge overlapping intervals | Sorted by start, then merged in one pass, and said why sorting first makes one pass enough. Named the case of touching intervals and chose to merge them. |
| Follow-up, input too large for memory | Proposed sorting chunks and merging them. Missed duplicates across chunks until asked. |
| Cache invalidation | Gave write-time invalidation with an expiry. On the late-invalidation follow-up, described stale reads and proposed versioned keys. |

*Tracy runs the coding task and the conversation in one interview, so approach is asked about while the code is on screen. Illustration with sample data*

The coding task and Tracy's conversation sit in one interview.

*Tracy asks about the trade-off behind a fix, so an engineer sees whether the candidate can explain a fix as well as produce it. Illustration with sample data*

The follow-up asks about the trade-off behind the fix, using the candidate's own words.

## What evidence does an engineering lead get?

An engineer reading the result can check it.

- A recording of both sides and a timestamped transcript behind every result.
- A written assessment for each question, with its reasoning.
- A ranking against the others who took the same interview, with strong candidates flagged automatically.
- One record to send on: resume match, interview score, strengths and gaps and the recording, shared by link or PDF.
- A person's last word: a reviewer can override a rejection or invite a candidate to interview again.

See [AI interview reports](/blog/ai-interview-reports) for how to read one.

For integrity, Tracy captures tab changes, abnormal eye tracking, live face detection, delay before answers, fullscreen exits and external screens, and shows the evidence to a reviewer. A signal is a prompt to look, never proof. Candidates are told about the recording on the join screen, and nothing is decided in the interview. See [AI interview cheating detection](/blog/ai-interview-cheating-detection) for how to handle a flag.

## How do you run it for hundreds of applicants from your own stack?

Each applicant starts on click, at any hour, with no scheduling and no recruiter present. The interview is ready in under 10 seconds. A dropped candidate can rejoin within 10 minutes (customers can configure this), a reminder goes out after a day and failed interviews are chased automatically.

Three ways to start an interview fit an engineering pipeline: an invite link, an apply page, or your own system through the API. Tracy also works beside Workable and Breezy HR through their chat connectors, so candidates stay in the ATS and shortlisted people are invited from chat. The [Connect page](/connect) has each guide, and [technical interviews](/use-cases/technical-interviews) shows how teams set this up.

## What stays with your engineers?

Tracy runs the first technical conversation. Your engineers keep three things.

1. **System design and team fit,** in a live round with someone senior.
2. **A blind read.** Before you trust the assessments, have one engineer read five or six transcripts and score them without seeing Tracy's. If they disagree, change the questions first.
3. **The decision.** A person decides from the evidence. Tracy publishes no bias audit, so treat the report as evidence to weigh and not a verdict.

For a few candidates a month, an engineer on a video call is likely cheaper; see [AI interview versus human interview](/blog/ai-interview-vs-human-interview).

## What does it cost, and how do you pilot it?

Tracy costs $1 per credit, and one credit covers each started 20 minutes of an interview that produced a result. A 34-minute interview takes 2 credits, which is $2, and 100 interviews of 20 minutes cost $100. The first 3 results are free with no card, there are no seats and no upfront cost, and a session with no answers is never charged. See the [pricing page](/pricing) for the current plan.

Pilot it on one role: name an engineer as owner, send the link to 20 applicants, and compare the reports with who a phone screen would have passed. Stop if the owner would change fewer than a quarter of the decisions (our rule of thumb).

Try one role on the [Connect page](/connect); the first 3 results are free.

Which path fits you:

- Hundreds of applicants for one role: [volume hiring](/use-cases/volume-hiring).

## Common questions

### What is an AI interview for a software engineer?

A two-way video interview run by an AI interviewer. It asks questions on the candidate's own stack, can include a coding task, and follows up on what the candidate says. The hiring team reads a recording, a transcript and a written assessment.

### Can an AI interview for software engineers include coding?

Yes. Tracy can run a coding task inside the same interview, in live code, SQL, debugging or multiple choice, then ask follow-ups about approach and trade-offs.

### How do you stop candidates reading answers from another screen?

Tracy captures tab changes, gaze, face detection, delay before answers, fullscreen exits and external screens, and shows the evidence to a reviewer. Treat a signal as a reason to look, and decide as a person.

### What does an AI interview for software engineers cost?

$1 per credit, one credit per started 20 minutes. The first 3 results are free, and there are no seats.
