    2. Interview Solver For Better Focus on Tech Interviews

    Overview

    The Interview Solver website is pretty solid on the subject – they're pros at real-time programming interviews and they've got you covered for LeetCode problems and extra features like companion mode (for using another device as a second screen) and document upload (so you can use and analyse additional info during the interview).

    Features

    Here’s what stood out to me:

    Feature

    Description

    Interview Copilot

    Gives real-time, structured responses.

    Undetectability

    Remains undetectable during screen sharing.

    Voice Transcription

    Transcribes both your voice and the interviewer's voice.

    Document Upload

    Upload and reference documents during interviews.

    Companion Mode

    Use any device as a second screen for code display and assistance from others.

    Pros

    • It's quick to get answers back and they seem really professional.

    • Global hotkeys were a really good addition, and they responded almost straight away.

    • It was invisible in screenshots and online meetings, which is pretty impressive.

    Cons

    Limitation/Issue

    Description

    Pricing

    The cost is high, and the free plan feels limited.

    Guidance

    It takes time to get comfortable with all the features.

    Answers

    Needs clicks or shortcuts to get answers, instead of auto-generating.

    Interface settings

    The transparency cannot be adjusted, sometimes freezes, and cannot even be found after minimising.

    Compatibility

    Once it wouldn't run on Mac computer.

    Verdict

    Interview Solver can be tricky to spot, even in Task Manager, but it handles LeetCode problems like a pro. The thing is, it's not the most stable, to be honest. Its workflow can be a bit erratic, and it does sometimes freeze or crash.

    If you do technical interviews a lot, I think it's a solid choice. The monthly subscription is reasonably priced at $39, but it does take a little time to get used to.

    3. Leetcode Wizard: Best Tech Interview Assistant Using Second Device

    Overview

    Leetcode Wizard uses custom AI models that are reportedly trained daily on real Leetcode interview questions. This special design makes it better than general-purpose language models (LLMs) like ChatGPT at certain tasks.

    Features

    Feature

    Description

    Invisible Operation

    Runs discreetly during screen-sharing sessions

    Undetectable hotkeys

    Can be controlled by undetectable hotkeys. Never have to leave the window.

    Web view for secondary devices

    Allows you to view all output on another device.

    Pros

    • Hotkeys made it easy to get help without breaking my focus.

    • The tool works on most coding platforms, so I didn’t have to switch tabs.

    • Many users say it’s fast and reliable during tough interviews.

    Cons

    1. If the assistant is using a smartphone, the screen is too small to see the answers properly and it can look a bit weird during the interview.

    2. If the extra device is a tablet or computer, it has to be placed to the side. If not, the candidate will get caught checking answers.

    3. Just so you know, you can only use Leetcode Wizard with dual devices during technical assessments to avoid detection. But some technical interview platforms (like CoderByte) spot it right away and make Leetcode Wizard useless.

    Verdict

    Leetcode Wizard offers a monthly subscription service priced at €49 (about $58), which seems fair and reasonable to me.

    I'm sure you'll agree that this tool definitely lives up to its technical promises. It solves a whole bunch of problems – even complex ones – really quickly, and it's super accurate and easy to understand. It's like having an engineer on call 24/7, ready to give guidance whenever you need it, which makes the learning process way faster.

    I think Leetcode Wizard works best on platforms that allow two devices or don't detect dual-device usage.

    4. CTRLpotato: For Staying Private During Tech Interviews & OAs

    Overview

    CTRLpotato is an invisible interview assistant that uses a context buffer – it's basically like a digital clipboard. You can add audio, screen captures, and text snippets. Then, at the touch of a button, you can send it all off to create one comprehensive answer which has all the info covered.

    Features

    Here’s a table showing the innovative features I found most useful:

    Pros

    1. Ease of use: It can automatically recognize and answer questions, and allows users to upload screenshots of the problem

    2. Quality of generated answers: Utilise cutting-edge AI models (detailed later) and let me pick any programming language (Python, Java, C++), so they can generate answers quickly and effectively. I've tested it with challenging Leetcode problems, and it performed exceptionally well.

    3. live interview capability: During the interview, CTRLpotato will display a compact, unobtrusive window that won't interfere with your screen sharing. If you want, you can also use your phone as a second screen to view responses.

    Cons

    Drawback/Challenge

    Description

    Visibility during dual devices

    Same as Leetcode Wizard, its dual devices mode can be spotted during live interviews.

    Lack of human touch

    Responses sometimes feel generic and machine-like.

    Emotional intelligence

    The tool can misinterpret intent and doesn’t always understand emotions.

    I noticed that the answers sometimes lacked warmth and didn’t connect with my background. The customization options are solid, but the responses felt templated compared to other platforms.

    Verdict

    CRTLpotato is a tech interview assistant that helps you prepare for and get through interviews. It lets you capture questions with just one click, record audio, highlight text and take screenshots. Just press a button and you'll get the answer you need. It gives you a little teaser, and then fills you in on the whole situation. Also, it always shows just your screen, with all the content in your workspace instead of a shared view.

    It supports a second-screen view, so you can access answers from your phone or tablet. This is great for situations where you don't want to turn on your camera or connect a second device.

    5. Beyz AI: Best for All-In-One Prep &I Interview Process

    Overview

    With just one keyboard shortcut, Beyz AI can instantly solve programming challenges. As an AI interview and coding assistant, it helps you solve any problem by writing code, breaking down logic, analysing time and space complexity, and designing optimal solutions.

    It can also handle the whole screening process and other stages, putting all the interview rounds into one tool for central management and tracking.

    Features

    Here’s a table showing the main features I found during my test:

    Core Functionality

    Description

    AI Interview Assistant

    real-time answering hints tailored to profile and interview context

    Coding Assistant (paid plan only)

    writing code, breaking down logic

    Invisible Desktop App (paid plan only)

    listens to all meetings and interviews, generates suggestions, and sends suggestions to devices

    Solo Practice

    practice anytime with the same context

    Interview Cheat Sheets

    pre-saved answers to copy for the future interview

    Pros

    • Straightforward setup and workflow

    • The audio transcription was both fast and highly accurate.

    • It looks like the responses were generated by a trained language model and were almost ready to be read aloud.

    • The whole thing was guided by step-by-step instructions and prompts (though the share button in the tab can be a bit tricky to locate)

    Cons

    Weakness

    Description

    Accuracy issues

    Sometimes the answers didn’t match the questions, which confused me.

    Response delays

    I noticed lags between my questions and the AI’s replies, which made the practice feel awkward.

    Inconsistent language performance

    The tool struggled with accents and technical terms

    Limitations in handling high- tier technical interviews

    All its self-introduction and other answer parts felt a little too simple to fit high-level positions.

    Verdict

    After testing and doing some research, we found that Beyz AI is a really practical and efficient solution. But when I actually went through a formal interview, I found that I needed to purchase a quarterly plan or an annual subscription – which are more expensive than the monthly plan – to unlock all the features.

    If you're not fussed about the price, Beyz AI has a bunch of features related to how you use the model, support after you've bought it, and it can be used in different languages.
