Mock Google Coding Interview with a Meta Intern

1. Interviewing.io

Interviewing.io offers a unique way to prepare for tech interviews with anonymous practice sessions led by senior engineers from companies like Google, Meta, and Amazon. These sessions are audio-only, paired with a collaborative coding environment, which eliminates bias and allows you to focus entirely on solving problems. The platform caters to candidates across all experience levels - from entry-level software engineers to senior roles like Staff Engineers and Engineering Managers. It covers a wide range of topics, including coding, system design, machine learning, and behavioral interviews. This focused approach is different from platforms like scale.jobs, which combine job search tools with AI and human expertise.

Pricing (Free/Paid Tiers)

You can solve over 200 FAANG-style problems for free using the AI Interviewer. For personalized coaching with senior engineers, prices start at $225 per hour, with multi-session bundles available. A 100% money-back guarantee is also included.

Feedback Type (AI/Peer/Expert)

Feedback is provided in two ways: free AI-driven sessions or paid coaching from experienced engineers at top tech companies. Human coaching sessions include 2–3 pages of detailed feedback and session recordings. As Aaron Farber, a Software Engineer at Meta, shared:

"interviewing.io was more than a small part of my success. Your platform gave me the comfort and confidence to treat my interviews like a fun, relaxing conversation over shared interests, rather than the terrifying psychological gauntlet that they started as."

Tech Role Suitability (Coding/Systems Design)

The platform is designed for roles requiring expertise in algorithms, data structures, system design, machine learning system design, front-end engineering, and engineering management. It’s particularly suited for experienced professionals aiming to fine-tune their skills for FAANG-level interviews. Zafir Khan, Director at WhatsApp (Meta), remarked:

"I think getting used to the pressure of an interview is the important part of preparation. And it's also the hardest to simulate. Interviewing.io has taken care of that for me!"

Free Trial Availability

Although there’s no free trial for human-led sessions, the AI Interviewer is available for free, allowing you to tackle over 200 problems. Additionally, you can access nine free chapters from the sequel to "Cracking the Coding Interview" before deciding to purchase paid sessions. In contrast, scale.jobs integrates free job search tools with human support, offering a broader range of services.

Why scale.jobs Wins

While Interviewing.io focuses on technical interview preparation, scale.jobs provides a more comprehensive approach to the job search process:

• End-to-end support: scale.jobs combines human assistants with ATS-optimized resumes and cover letters to streamline your job search, not just interview prep.
• Flat-fee pricing: No hourly coaching fees - scale.jobs offers a one-time payment model with transparent proof-of-work screenshots and refunds for unused credit.
• AI-powered tools: Resume tailoring and cover letter generation ensure your application passes ATS filters, complementing your interview preparation.
• Time-saving assistance: Real human virtual assistants handle everything from applications to portal submissions, saving you over 20 hours per week.

Filipe Gonçalves, a Software Engineer at Google, emphasized its impact:

"Pramp definitely played a role in my performance. Nothing beats mock coding interviews... I ended up with offers from both Google & Microsoft."

This specialized focus sets Pramp apart from platforms that offer broader job search tools.

Free Trial Availability

Pramp’s free model allows users to start practicing right away with monthly credits. Unlike platforms like scale.jobs, which provide comprehensive job search support, Pramp focuses solely on interview preparation through peer collaboration.

Why scale.jobs Wins

While Pramp excels at interview practice, scale.jobs offers a complete job search solution, going beyond just preparation:

• Human-powered applications: Virtual assistants handle your job applications across various platforms, saving you over 20 hours a week. They even provide proof-of-work screenshots.

4. MockAI

MockAI, developed by MockThatInterview, combines the precision of AI with the expertise of industry professionals to deliver a thorough interview evaluation. While the AI provides real-time scores for clarity, confidence, and content, seasoned professionals from top companies like Google, Meta, and Amazon step in with live feedback and insider advice. Though MockAI focuses on refining your interview performance, scale.jobs offers a broader approach to your entire job search experience.

Pricing (Free/Paid Tiers)

MockAI operates on a paid subscription model, with pricing tiers based on the number of practice sessions. Subscribing gives you monthly access to both AI-driven feedback and expert-led sessions.

Feedback Type (AI and Expert)

5. HireVue

HireVue is a platform tailored for corporate hiring, focusing on large-scale enterprise needs rather than individual job seekers aiming for tech roles. While candidate assessments are free, the platform's high corporate fees underscore its design for organizations conducting thousands of interviews annually. This makes it distinct from more candidate-focused platforms like scale.jobs.

Feedback Type (AI-Driven)

HireVue uses AI algorithms to evaluate candidates by analyzing their speech patterns and facial expressions. For technical positions, its CodeVue module adds a layer of coding assessment, though this feature significantly increases costs, reinforcing its appeal to corporate users. While the AI-driven feedback provides insights, its primary goal is to streamline the screening process for employers rather than assist candidates directly.

Tech Role Suitability (Coding Assessments)

HireVue supports technical hiring with coding challenges integrated into its one-way video interview format via the CodeVue module. The platform accommodates interviews in more than 40 languages and holds a 75.7% share of the enterprise hiring market. It’s also the only virtual interviewing provider authorized under FedRAMP for government contractors, further cementing its enterprise focus.

Why scale.jobs Stands Out

While HireVue caters to large corporations, scale.jobs is designed specifically for individual tech job seekers. Here’s how it sets itself apart:

• Affordable Options: Access AI-powered resume tools for just $9/month or opt for flat-rate human reverse recruiter services, complete with refunds for unused credits.
• Interview Preparation: Use a free interview question predictor to anticipate questions from companies that rely on platforms like HireVue.
• Application Assistance: Human virtual assistants handle ATS-optimized application submissions, providing proof-of-work screenshots and real-time WhatsApp updates.
• Comprehensive Job Search Tools: Beyond interview prep, scale.jobs offers tailored resumes, cover letters, salary insights, and portfolio creation.
• Transparency: Real-time updates and time-stamped proof of work, offering a clear contrast to HireVue’s opaque AI scoring system.

6. InterviewBuddy

InterviewBuddy combines human expertise with AI-powered tools to help candidates prepare for technical interviews. With over 200,000 professionals served and access to 4,500+ industry experts from companies like Google, McKinsey, and Deloitte, the platform is a go-to choice for interview practice. However, while InterviewBuddy focuses solely on mock interviews, scale.jobs offers a more comprehensive job search solution.

Pricing (Free and Paid Options)

InterviewBuddy uses a pay-per-session model, starting at just $1.00 per session. Expert-led sessions begin at $23.99 and last between 30 and 90 minutes. There's also a free tier and a free trial available - no credit card needed. Unlike subscription-based platforms, this model allows users to pay only for what they use, making it a flexible option for budget-conscious candidates.

Feedback Type (AI and Expert Insights)

The platform uses a hybrid feedback approach, blending AI sentiment analysis with personalized input from experts. Each session includes a performance scorecard, a growth roadmap, a recruiter-ready answer bank, and a session recording. According to InterviewBuddy, 82% of users secure interviews or job offers within three months, and 9 out of 10 report feeling more confident after just one session.

Tech Role Suitability (Coding and Systems Design)

InterviewBuddy supports over 350 technical roles, with a strong emphasis on Full Stack Development, Data Science, DevOps, and Cloud Computing. It offers specialized 1:1 coding sessions with experts from top-tier companies, providing live coding practice and systems design preparation. Users frequently highlight the value of expert feedback and the ability to review recorded sessions for further improvement.

Why scale.jobs Stands Out

While InterviewBuddy shines in interview preparation, scale.jobs goes beyond mock interviews to offer a full job search toolkit. Here's how it differentiates itself:

• Comprehensive Job Search Support: Handles applications, ATS-optimized documents, and follow-up reminders.
• Flat-Fee Pricing: A one-time payment model with refunds for unused credits, unlike InterviewBuddy’s per-session costs that can add up.
• Free Tools: Includes a free interview question predictor, allowing preparation without paying for each session.
• All-in-One Platform: Offers tailored applications, salary insights, portfolio creation, and dedicated WhatsApp support with time-stamped proof-of-work.

While InterviewBuddy is ideal for honing interview skills, scale.jobs provides a broader range of tools to navigate the entire job search process.

7. LeetCode Mock Assessments

LeetCode is tailored for developers, offering solo, timed assessments with a library of over 2,000 problems, including company-specific question sets from tech giants like Google, Amazon, and Microsoft. While LeetCode focuses exclusively on coding challenges, platforms like scale.jobs provide a more comprehensive approach to the job search process.

Pricing (Free and Paid Options)

LeetCode has a free tier that grants access to over 300 coding problems and community discussions. However, structured mock assessments and advanced features require a Premium subscription. The Premium plan costs approximately $35 per month, with an annual option available at a reduced rate.

Although there’s no formal free trial, the free version offers a solid starting point for exploring the platform.

Feedback Type (AI-Powered)

LeetCode relies entirely on automated, AI-driven feedback. Its "Lightning Judge" feature provides instant performance evaluations, while "Ask Leet", an AI coding assistant, helps debug and optimize code. Premium subscribers get 500 extra monthly credits to access advanced AI tools. The platform offers timed, company-specific practice sessions designed to simulate real interview pressure. Unlike platforms like Pramp, which include peer interaction, or InterviewBuddy, which provides expert-led sessions, LeetCode focuses solely on individual practice without human feedback or follow-up questions. This makes it a specialized tool for honing coding skills under realistic conditions.

Tech Role Suitability (Coding-Centric)

LeetCode is best suited for mid-to-advanced developers aiming for roles at FAANG companies, particularly those that emphasize data structures and algorithms. It’s especially effective for practicing company-specific coding challenges. However, its offerings are limited when it comes to systems design, behavioral interviews, or AI-related roles, where conversational skills and open-ended discussions are often critical. This narrow focus makes LeetCode a go-to platform for algorithm mastery, but less versatile for other aspects of technical interview preparation.

Why scale.jobs Stands Out

While LeetCode is excellent for sharpening coding skills, scale.jobs takes a broader approach, covering the entire job search journey. Here’s how it differs:

• Comprehensive Job Search Support: Beyond interview prep, scale.jobs handles applications, ATS-friendly resumes, personalized cover letters, and follow-ups.
• Human Assistance: Unlike LeetCode’s automated tools, scale.jobs employs trained reverse recruiters who manage submissions and provide updates via WhatsApp with time-stamped proof of activity.
• Transparent Pricing: A one-time flat fee includes unused-credit refunds, avoiding the recurring $35 monthly charges of LeetCode Premium.
• Free Resources: Offers tools like an interview question predictor and salary insights at no cost, making it easier to prepare without committing to a paid plan.

LeetCode is an excellent resource for developers looking to fine-tune their algorithm skills, but for a more holistic job search experience, scale.jobs offers the human touch and range of tools needed to secure the role.
