Question 1

What is Composur and how does it work?

Accepted Answer

Composur is a mock interview tool for software engineers. You talk to an AI interviewer out loud, and it asks follow-up questions based on what you say. Some rounds include a coding problem you solve in the browser.

Pick a role, interview type, and level, then start. When you finish, you get a recording, a transcript, an overall score, and notes on what went well and what to work on.

Question 2

Do I need an account to read the FAQ?

Accepted Answer

No. The FAQ and support pages are open to everyone. You need an account to run interviews, save recordings, or send a support ticket.

Question 3

What browser and hardware do I need?

Accepted Answer

A recent version of Chrome, Safari, or Edge and a working microphone. Firefox is not currently supported. A webcam is optional. Speech recognition runs on your device, so the first session downloads a speech model and may take a moment to start. Run the voice check before your first interview to make sure your mic works.

Question 4

How do I create an account or sign in?

Accepted Answer

Use Start free or Log in at the top of the page. You can sign up with your email address and confirm it with a one-time code.

Question 5

How do the AI mock interviews work?

Accepted Answer

The interviewer asks a question, listens to your spoken answer, and follows up on what you said, the same way a person would ask you to explain a trade-off or go deeper on a decision. Coding rounds add a problem you solve and run during the conversation.

Question 6

Can I choose the role, level, and interview type?

Accepted Answer

Yes. Before each session you choose the role you're preparing for, your experience level, and the kind of interview you want to practice.

Question 7

How do speech recognition and the interviewer's voice work?

Accepted Answer

Your answers are transcribed on your device as you speak, and the interviewer's replies are read aloud with a voice that also runs in your browser. The transcript is what's sent to our servers to generate the next question and your feedback.

Question 8

How is my interview scored?

Accepted Answer

After the session you get an overall score out of 100 plus dimension scores that depend on the interview type. You also get a short summary, your strengths, and the gaps worth working on next.

Question 9

What programming languages can I use in coding rounds?

Accepted Answer

Python, Java, and C++.

Question 10

Is code execution isolated?

Accepted Answer

Yes. Each run executes in a short-lived, sandboxed container with limits on CPU, memory, and run time. It has no access to other users' code or data.

Question 11

Can I run my code against test cases?

Accepted Answer

Yes. During a coding round you can run your solution and see which test cases pass before you move on.

Question 12

What does the code editor include?

Accepted Answer

The editor is Monaco, the same editor used in VS Code, with syntax highlighting, bracket matching, and auto-indentation.

Question 13

What's in the question bank?

Accepted Answer

Practice questions across roles and difficulty levels, covering coding, system design, and behavioral topics. Some questions are tagged with the companies known to ask them.

Question 14

How do I find questions to practice?

Accepted Answer

Search by keyword or use the filters to narrow the list down to what you want to work on.

Question 15

Can I get feedback on a single question?

Accepted Answer

Yes. Open a question, write your answer, and submit it to get a score and written feedback without running a full interview.

Question 16

Are system design questions included?

Accepted Answer

Yes. The question bank includes system design problems alongside coding and behavioral questions.

Question 17

Where are my past interviews saved?

Accepted Answer

Finished interviews appear under Recordings, where you can replay them and read the transcript. Your scores over time are on the Analytics page.

Question 18

Can I share an interview with someone?

Accepted Answer

Yes. From a recording, you can create a share link to send to a mentor or friend. You can turn the link off at any time.

Question 19

How does score tracking help me improve?

Accepted Answer

Analytics shows how your scores change across sessions, so you can see which areas are improving and which ones still need practice.

Question 20

Can I replay a session and read the transcript?

Accepted Answer

Yes. Every recording comes with a timestamped transcript, so you can jump to a specific answer and listen to it again.

Question 21

Do you sell my data or use it for AI training?

Accepted Answer

No. We don't sell your personal information, recordings, transcripts, or code, and none of it is used to train AI models.

Question 22
