12/In plain words

What is RoundAlpha?

α

RoundAlpha is an AI mock interview platform for job seekers. You upload your CV, name the role you're going for — a target company and job description are optional — and an AI interviewer runs a live voice interview: questions drawn from your own experience, follow-ups when an answer is thin, and, in a full round, a hands-on coding exercise plus either a system design task or a second coding exercise. When it ends you get a scored report with the reason behind every score. Hiring teams use the same interviewer to screen applicants through a link.

the short version
Questions people ask
01How does an AI mock interview on RoundAlpha work?

You upload your CV and choose the role. The AI interviewer then holds a live voice conversation with you: it asks questions based on your own experience, follows up when an answer skips something, and keeps the interview to time. A full round also includes a hands-on coding exercise, plus either a system design task or a second coding exercise.

02Is it a real spoken conversation?

Yes. You answer out loud and the interviewer responds in real time, the way a human interviewer would, including follow-up questions.

03What does the report show?

Five skills scored out of ten, a verdict on each question with the reason behind it, and one concrete thing to change before your next attempt.

04Can I practice for a specific company or job?

Yes. Name the company and paste the job description, and the interview is tailored to that role.

05Can I apply for jobs on RoundAlpha?

Yes. Browse open roles, apply with the CV in your account, and keep your applications and interview invitations together in your dashboard.

06How much does RoundAlpha cost?

Free to start with a short taster round. Starter: 3 interviews a month for $10 or ₹499. Pro: 7 interviews a month for $20 or ₹999. Cancel anytime.

07Is my CV kept private?

Your CV is used only to build your interview and report. It is never shared, and you can delete it and your transcripts whenever you like.

08Can companies use RoundAlpha to interview candidates?

Yes. A hiring team sends each applicant an interview link and gets back a scored report with the full transcript, visible only to that team. It is free while companies are onboarded by hand.

Your first try shouldn’t be the real one. Make it here.
