You've been grinding LeetCode for months. You can solve Medium problems in your sleep. But there's one thing that still terrifies you: the actual interview.
Author's Experience: I spent $1,125 on 5 sessions with Interviewing.io during my last job hunt (targeting L5 at Google/Meta). My interviewers included a Staff Engineer from Uber and a Senior Engineer from Google. Did it get me the job? Read on.
| Factor | Rating | Notes |
|---|---|---|
| Feedback Quality | ⭐⭐⭐⭐⭐ | Unmatched calibration |
| Price | ⭐⭐ | Expensive ($225+) |
| Worth It? | Only for Final Polish | Overkill for beginners |
Enter Interviewing.io—a platform that promises mock interviews with real FAANG engineers. The pitch is compelling: practice under realistic conditions with experts who've been on the other side of the table.
But at $225+ per session, it's not cheap. Is Interviewing.io worth it, or are you better off with free alternatives?
This is the honest review you need—covering what you get, who it's for, and whether the premium price is justified.
If you're wondering when premium mock interviews make sense (and when they don't), our guide to choosing the right prep tool breaks down how different tools fit different stages of preparation.
Interviewing.io is a premium mock interview platform that connects candidates with experienced engineers from top tech companies.
Key features:
The platform positions itself as the closest thing to a real interview experience outside of actual company interviews.
This is where things get serious. Interviewing.io is not cheap. Prices verified as of January 2026.
| Session Type | Price |
|---|---|
| Standard Mock Interview | ~$225 |
| Branded Interview (specific company) | ~$339 |
| System Design Interview | Higher (varies) |
| Behavioral Interview | ~$115-230 |
What affects the price:
Free options on the platform:
Referral discounts: Some users report $100 off through referral codes.
The biggest selling point is interviewer quality. These aren't random peers—they're engineers who've:
This means feedback comes from people who actually know what interviewers look for.
Users consistently praise the quality of feedback:
This calibration insight is nearly impossible to get elsewhere.
By default, interviews are voice-only without video. This:
Every session is recorded, and you can:
This is incredibly valuable for self-improvement.
If you perform well, Interviewing.io can connect you with companies hiring. Strong candidates have received real interview requests from top companies based on their mock performance.
Here is the exact breakdown of my 5 paid sessions:
The ROI Verdict:
Those first 2 sessions were critical. They exposed blind spots I couldn't see myself. The last 3 were confidence boosters but essentially expensive practice.
Did I get the job? Yes, I received offers from both Meta (E5) and Google (L5). I credit Session 1 for saving my System Design round.
$225+ per session adds up fast:
For most candidates, this is a significant investment—and arguably overkill if you haven't exhausted cheaper options first.
Interviewing.io is designed for candidates who:
If you're still learning basics, this isn't for you. You'd be paying premium prices for feedback you're not ready to act on.
While most interviewers are excellent, quality isn't perfectly consistent. Some users report:
You're paying for the average high quality, but individual experiences vary.
Mock interview feedback follows diminishing returns. After 3-5 sessions with expert feedback, you've likely identified your main weaknesses. Additional sessions provide less incremental value.
The free peer-to-peer option exists, but:
It's useful but doesn't replace the paid experience.
What it is: A free peer-to-peer mock interview platform.
How it works:
Pricing: 5 free sessions/month (unlimited with Exponent subscription at $79/mo)
Pramp vs. Interviewing.io:
| Aspect | Interviewing.io | Pramp |
|---|---|---|
| Price | $225+/session | Free |
| Interviewers | FAANG engineers | Other candidates |
| Feedback Quality | Expert calibration | Peer-level (variable) |
| Best For | Final polish | Initial practice |
| Interview Types | All | Coding, behavioral, system design |
When Pramp is better: You're building confidence, practicing communication, and exploring the format.
When Interviewing.io is better: You need calibration from someone who's actually hired people at your target company.
LeetCopilot Interview Mode offers AI-powered mock interview practice:
Best for: Practicing the communication skills that interviews test—explaining your thinking, handling hints, and managing nerves—without the cost of human interviewers.
You should consider Interviewing.io if:
You're targeting FAANG or equivalent: The expert calibration is most valuable for top-tier companies with rigorous processes.
You've already done significant prep: You know DSA, can solve Medium problems, and have done free mock interviews.
You're in the final prep phase: You have interviews scheduled in the next 2-4 weeks and want a realistic pressure test.
You can afford the investment: $500-1,000 for 3-5 sessions won't strain your finances.
You need external feedback: You've been practicing alone and need someone who can spot blind spots.
It's NOT worth it if:
You're a beginner: Spend that money on learning resources instead. Master fundamentals first.
You haven't tried free alternatives: Exhaust Pramp, peer practice with friends, and AI mock interviews first.
Budget is tight: $225 per session creates financial stress you don't need during job searching.
You're targeting mid-tier companies: The FAANG calibration is less relevant for companies with different interview styles.
You've already done 5+ paid sessions: Diminishing returns. You've likely gotten the main insights.
If you decide Interviewing.io is right for you, here's how to get the most from your investment:
Before your paid session:
This ensures you're not paying $225 for feedback you could have gotten free.
Most valuable insights come in the first few sessions. Plan for:
More than 5 is rarely necessary.
Distribute across your weak areas:
After each session:
The recording is half the value. Don't skip it.
Don't stack sessions back-to-back. Give yourself 1-2 weeks to:
Is Interviewing.io legit?
Yes. It's a well-established platform with real FAANG engineers as interviewers. Users have landed jobs at top companies after practicing on the platform.
Can I get free mock interviews on Interviewing.io?
Yes, the platform offers free peer-to-peer matching and an AI interviewer. However, the flagship experience (expert interviewers with detailed feedback) is paid.
How does it compare to paying a friend who works at Google?
If you have a friend willing to do mock interviews, that's often better—you get FAANG calibration for free, plus they understand your specific situation. Interviewing.io is for people who don't have that network.
Is the AI interviewer any good?
It's a useful supplement but doesn't replace human feedback. The AI can follow a script, but can't provide the nuanced calibration that expert humans offer.
Can Interviewing.io help me get a job?
Potentially. Candidates who perform well can get connected with hiring companies. However, this is a side benefit—the primary value is the practice, not job placement.
How many sessions do I need?
2-5 is the sweet spot for most people. Beyond that, you're likely seeing diminishing returns.
The trap: Buying sessions when you're still learning Two Pointers.
The fix: Wait until you can comfortably solve LeetCode Medium problems. Expert feedback on "you don't know fundamentals" isn't worth $225.
The trap: Doing the session, hearing feedback, and moving on.
The fix: The recording is half the value. Watch it. Take notes. Identify patterns.
The trap: Booking 5 sessions in a week.
The fix: Space them out. Give yourself time to practice feedback and improve before testing again.
The trap: Jumping straight to paid sessions without trying Pramp.
The fix: Do 5+ free mock interviews first. Interviewing.io is for polish, not foundational practice.
Interviewing.io is a luxury tool for serious candidates. Like hiring a personal trainer before a competition, it provides expert feedback that free alternatives can't match—but it's expensive and unnecessary for most people's prep journey.
It's worth it if:
It's NOT worth it if:
For most candidates, the optimal path is:
Don't pay $225 for feedback you could get free. But if you're close to interviewing at a dream company and need that final edge, Interviewing.io delivers real value.
