AI mock interviews that talk back, then coach you to better answers
Beginner
What is Merra?
Merra is a career tool. Merra runs spoken AI mock interviews with a conversational interviewer who asks follow-ups and scores each answer out of 100. Coaching reports include transcripts, recordings and rewrites, with separate tracks for job interviews and visa credibility checks.
Merra is an AI mock interview platform built around a conversational interviewer named Hope who asks questions out loud, listens to your replies, and follows up the way a real interviewer would. Every session ends with each answer scored out of 100 and paired with a specific piece of coaching. The product covers two very different audiences: job seekers preparing for first-round interviews at firms including Google, Amazon, Meta, Goldman Sachs, McKinsey, Deloitte, PwC, JPMorgan Chase, Microsoft and Netflix, and visa applicants rehearsing credibility and embassy interviews for UK pre-CAS checks, US F-1, B1/B2, H-1B and J-1 routes. The mechanic that separates Merra from a question bank is the feedback loop. In Coach mode the interviewer pauses after each answer and gives one thing to keep and one thing to fix, which suits people building a baseline. Interview mode keeps going without help and saves notes for the end, closer to a real first round. Beast mode pushes on weak answers and refuses to let vague claims pass. Reports show a scored breakdown by criterion, a transcript and recording, and sample rewrites such as reframing a loan answer around fund-holding dates and documented savings. Criteria shift with the interview type: job mocks score structure, communication and problem-solving, while visa mocks score intent, consistency, course knowledge and financial credibility. Practically, a session takes only a few minutes. The company pages give a sense of format before you start, with role-specific prompts like a URL shortener design question for a Google software engineer mock or a churn diagnosis case for Deloitte. Merra publishes aggregate figures from real sessions, claiming a median gain of 12 points and a move from a 48 median on the first mock to 60 by the fifth. It sits between interview question banks, which are static, and human coaching, which is expensive and hard to schedule. Merra's weakness is depth: sessions are brief, and the strongest reports sit behind paid credits, so free users see scores and a single fix rather than the full rewrite set.

Start with Hope for guided coaching after each answer, switch to James for an uninterrupted run through, or use Chris when you want blunt pressure on weak answers.4Preview a target company's format
Browse the company interview pages to see the kinds of questions and role formats Merra builds mocks around, such as system design at Google or behavioural rounds at Goldman Sachs.
5Speak through the interview
Answer out loud as the AI asks questions and pushes back with follow-ups. Sessions run only a few minutes, so treat each one as a focused rep rather than a full interview.6Review your scored report
