Interviewcoder: the invisible AI tool that aids remote technical interviews

General Introduction

Interviewcoder is an AI-assisted tool designed for technical interviews, designed to help users quickly generate solutions, optimize code and debug in real-time during programming interviews. It runs as an invisible desktop application that users can use on screen-sharing platforms such as Zoom and Google Meet without being detected. The tool supports screenshot analysis of problems, generates code with detailed comments, and provides optimization suggestions from O(n²) to O(n). Available for LeetCode, HackerRank, and other platforms, priced at $60 per month, it emphasizes efficiency and stealth, and is popular with job seekers and developers.

Function List

• Problem Screenshot Analysis: Intercept interview questions via shortcut keys, AI automatically extracts the questions and generates solutions.
• Code generation and commenting: Provide code with detailed comments to simulate the natural thinking process and facilitate interpretation by the user.
• Real-time code optimization: Analyze user code and propose complexity optimizations, such as replacing nested loops with hash tables.
• Invisible mode of operation: Invisible during screen sharing, supports shortcut key operations to avoid being noticed by the interviewer.
• Multi-Platform Compatibility: Support for LeetCode, HackerRank, CoderPad and other common interview platforms.
• Debugging Support: Identify errors and provide optimized comparison versions based on screenshots of user code.

Using Help

Installation process

Interviewcoder is a desktop application that requires the following steps to install:

1. Visit the official website and register
   Open your browser, enter the URL https://www.interviewcoder.co/ and click on the "Subscribe Today" button to register for an account and subscribe to the service ($60 per month). You will receive a download link after successful registration.
2. Download the application
   Depending on the operating system (macOS, Windows or Linux), download the corresponding installation package from the official website. macOS users download the.dmgDocumentation, download for Windows users.exeDocumentation.
3. installer
   • macOS: double-click.dmgDrag the Interviewcoder file into the Applications folder. After installation, you may need to go to "System Preferences > Security & Privacy > Privacy > Screen Recording" to enable permissions.
   • Windows (computer): double-click.exefile and follow the prompts to complete the installation without additional permissions.
   • Linux: After unzipping the installation package, you may need to run thexhostcommand to ensure permissions, refer to the official website for instructions.
4. triggering program
   After the installation is complete, open Interviewcoder and enter the account password you registered with to log in and enter the main interface.

Main function operation flow

1. Problem screenshots and solution generation

• procedure::
  1. Press the shortcut key when you come across a programming question in an interview⌘ + H(macOS) orCtrl + H(Windows) Capture screen.
  2. Up to 2 screenshots can be saved, and the screenshots will be displayed on the app screen to ensure that the title is complete.
  3. check or refer to⌘ + ↵(macOS) orCtrl + Enter(Windows) Trigger AI analysis.
  4. After a few seconds, the interface displays the complete solution, for example:

     def twoSum(nums: List[int], target: int) -> List[int].
     seen = {} # Hash table storing values and indexes
     for i, num in enumerate(nums):
     complement = target - num # Compute target difference
     if complement in seen.
     return [seen[complement], i] # find match return index
     seen[num] = i # if not found, then store current value
     return [] # return empty list for no solution
     

• specificities: The code comes with detailed annotations that mimic human problem solving, allowing users to directly copy and interpret them fluently.
• Usage Scenarios: For LeetCode type questions to quickly cope with time pressure.

2. Code optimization and debugging

• procedure::
  1. To display the code you wrote on the screen, press again the⌘ + HScreenshot.
  2. check or refer to⌘ + ↵Submit, and the AI will analyze the code and give suggestions for optimization.
  3. For example, if the user code is:

     def twoSum(nums, target).
     for i in range(len(nums)): for j in range(i + 1, len(nums)): for
     for j in range(i + 1, len(nums)): if nums[i] + nums[j] == target.
     if nums[i] + nums[j] == target.
     return [i, j]
     return []
     

     The AI will prompt, "Current time complexity O(n²), can be optimized to O(n)" and provide an optimized version as above.

• specificities: Provide before-and-after comparisons to explain optimization logic (e.g., hash tables to reduce loops) to help users understand.
• Usage Scenarios: Improve code quality quickly when interviewers ask for optimization.

3. Stealth operations and window management

• procedure::
  1. check or refer to⌘ + B(macOS) orCtrl + B(Windows) Toggles the state of the application to show and hide.
  2. utilization⌘ + arrow keysMove the window position to ensure that the code area is not obscured and that the line of sight is natural.
  3. When screen sharing, the app is not visible to Zoom (versions below 6.1.6), Google Meet, etc.
• specificities: Ensure covertness and avoid mouse operations that expose traces of use.
• Usage Scenarios: Staying focused and unnoticed in remote interviews.

caveat

• Permission settings: macOS users need to make sure the screen recording permission is enabled, otherwise the screenshot function will not work.
• Shortcut key conflicts: If the shortcut keys conflict with other software, you can customize them in the settings.
• network requirement: Stable network connectivity is required and AI analytics rely on cloud computing.
• version compatibility: Zoom 6.1.6 and above may detect the application and it is recommended to downgrade.

practical skill

• Practice using shortcuts before the interview to ensure smooth operation.
• Move the window to the corner of the screen to reduce eye drift.
• If the interviewer asks for ideas, it is both natural and professional to directly restate the contents of the code comments.

With these steps, users can quickly get up to speed with Interviewcoder in technical interviews, whether it's generating code or optimizing a solution to meet the challenge efficiently.
