Problems sourced from real interviews at Google, Meta, Amazon, Apple, and Microsoft in the last 6 months.
•HOW IT WORKS
Three steps to a better interview
Pick your company and level
Google, Meta, Amazon, and more. Problems are calibrated to SDE-1, SDE-2, or SDE-3+ difficulty.
Code while Alex watches
Alex asks follow-ups, challenges your approach, and checks your communication. Just like a real FAANG engineer.
Get your signal
Hiring signal plus 12 dimension scoring covering code, communication, DSA, optimization, and more.
•WHY INTERVIEWSKOOL
Solving LeetCode at home is not the same as interviewing
Interviewing is a different skill
Some people solve Hard problems on LeetCode but freeze up in a real interview. Interviewing requires practice under pressure, with someone watching and asking questions.
AI that pushes back
Alex counters your approach, asks follow-ups where required, and probes your reasoning. A blog post or LeetCode editor will never challenge you like this.
Feedback better than human mockers
Human interviewers give vague feedback. InterviewSkool scores 12 dimensions with specific, actionable insights after every session.
10x better than LeetCode alone
LeetCode builds pattern recognition. InterviewSkool builds interview performance. You need both, but only one simulates the real thing.

•SEE WHAT HAPPENS
Here's what a real session looks like
Alex doesn't just give you a problem and disappear. He asks follow-ups, challenges your approach, and pushes you to think deeper, just like a real FAANG interviewer.
Here's your problem: Given an array of integers, find two numbers that add up to a target. Walk me through your approach before you start coding.
I'd use a hash map. For each number, check if the complement exists in the map. If yes, return both indices. If not, add the number to the map.
Good approach. What's the time complexity? And what happens if there are multiple pairs that sum to the target, which one do you return?
O(n) time, O(n) space. For multiple pairs, I'd return the first pair found since we iterate left to right.
What if the interviewer says they want the pair with the smallest second index? How does that change your solution?
