Prept
Read full descriptionHide full description
The interviewer asks you to talk about a time you failed. You nail it. Then comes one follow-up question, and the answer that felt rock solid falls apart in your hands. Those five seconds decide interviews. Prept is the only app built to train for them. THE FOLLOW-UP IS WHERE INTERVIEWS ARE WON OR LOST Most prep stops at your first answer. Real interviewers never do. They hear "we delivered on time" and ask how, then watch you scramble. Prept's interviewer reads what you actually said and goes straight for the weakest claim. Say something vague and it asks for the specific. Make a leap and it asks you to connect the dots. Try to dodge and it notices. When you're done, you get a turn-by-turn debrief showing where you held firm, where you softened, and where you cracked, with your own words quoted right back to you. Stumbling here is free. Stumbling in the real room is not. WHAT MAKES PREPT DIFFERENT A hiring manager cross-examines you in character, then a debrief shows you where you held and where you cracked. Nothing else does this. Real coaching between every attempt, not just a score. A program that adapts to your gaps instead of a generic track. Feedback about what you said, not how you sounded. Model answers built from your words, not someone else's script. Your audio never leaves your phone. Complete privacy. No cheat sheets. No shortcuts. You put in the reps. THE PRACTICE LOOP Speak for 60 seconds on a real scenario. "Walk me through your resume." "Why should we hire you?" Answer it the way you would in the actual room. Then the coaching hits. "Your opening buried the point. Lead with the outcome." "You claimed results but gave no evidence. Add one number." You get two concrete rules for your next attempt, a framework showing what to cover, and a rewritten version of your own answer so you can hear what sharper sounds like. You try again with the coaching in front of you. Your scores update across five dimensions: Clarity, Structure, Conciseness, Confidence, and Impact. Not how you sound. What you said. Did you make your point or wander around it? Did you back your claim or leave it hanging? Then the follow-ups come, and you go again. WHAT YOU CAN PRACTICE Behavioral questions. "Tell me about yourself." "Describe your biggest achievement." "What's your biggest weakness?" You learn the STAR method by actually using it, not by reading articles you bookmarked and never opened. Situational and competency questions. "How would you handle a stakeholder who won't budge?" "Your project is behind schedule and leadership wants answers." The high-pressure moments where composure counts. Workplace conversations. Status updates that don't ramble. Feedback that actually lands. Saying no without burning the relationship. Asking for a promotion with evidence instead of hope. YOUR TRAINING PROGRAM Most apps hand you a question bank and wish you luck. Prept builds a program around your gaps. It starts with a 60-second diagnostic. That single answer tells Prept more about how you communicate than any self-assessment ever could. From there it builds a plan that meets you where you are, targets your weak spots, and gets harder as you earn it. Foundation builds the core habits, like structuring your answers and cutting the filler. Pressure brings in tougher scenarios and live follow-ups. Advanced sits you across from skeptical interviewers, where how you hold up matters as much as what you say. You don't pick your difficulty. You earn it. If a skill slips, your next session adjusts. You never waste a rep on the wrong thing. FREE TO START Take the 60-second diagnostic. See where you stand. Preview your training program. Then decide if you're ready to start getting ready.

Sotto

Sotto is a live conversation copilot built specifically for IT and enterprise professionals in job interviews โ not another generic coding-interview tool. WHY SOTTO IS DIFFERENT Every other "AI interview copilot" on the App Store is built for software engineers answering LeetCode-style questions. Sotto is built for the world of enterprise IT: tenant migrations, identity governance, compliance frameworks, and the vocabulary that actually comes up in those interviews โ M365, Entra ID, Intune, NIST, FISMA, ATO, CMMC, and more. HOW IT WORKS 1. Add your background. Your name, role, and a few lines about your real experience โ Sotto answers as you, grounded in what you've actually done, not as a generic candidate. 2. Paste the job description. Before your interview, drop in the role you're interviewing for so Sotto's suggestions speak that role's exact priorities and terminology. 3. Just talk. Sotto listens live. When the interviewer pauses, a quiet suggested answer appears in your own voice โ no typing, no tapping, nothing to fumble with mid-conversation. BUILT FOR PRIVACY Speech is transcribed entirely on-device using Apple's Speech framework. Your audio never leaves your device. Only the text of the conversation is sent to generate a response, and only when you ask for one. BUILT FOR IPAD Prop your iPad on a stand during a video interview and glance down when you need it. The split transcript-and-response layout is designed for exactly this โ not squeezed onto a phone screen as an afterthought. WHO IT'S FOR IT systems engineers, cloud administrators, compliance and security professionals, and anyone interviewing for enterprise IT roles who wants a quiet second voice that actually understands the job. Sotto requires your own OpenAI API key, stored securely in your device's Keychain. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
