AI mock interviews
for software engineers.
Larpy builds your interview for the exact job: behavioral, coding that actually executes, system design. Graded on what ran and what you said.
▍
The loop, the way companies run it.
Every company's process is mapped round by round, so you rehearse the seat you're actually walking into.
The screen
A recruiter call on your background, then a technical phone screen with a shared editor.
The coding rounds
Live problems where the talk matters as much as the code. Your solution runs for real.
The onsite
System design and the behavioral gauntlet, back to back, against the company rubric.
Asked in the loop.
More than 300 reported questions on file, each tied to a company and a round. These are four of them.
Walk me through the architecture of a project on your resume
Design the Facebook News Feed (generation, ranking, fan-out).
Ownership: tell me about a time you took on something outside your job scope, or owned a mistake end-to-end.
Design an end-to-end infrastructure service from a one-line requirement, such as a monitoring or metrics service, scoping it yourself before you draw anything.
Every question carries a source. The interviewer asks them the way a person would, then follows up on your answer.
21 companies, 114 rounds.
Each one opens the company's mapped loop: rounds, timing, reported questions, and a mock tailored to that seat.
Straight answers.
Does the code actually run?+
Yes. Coding rounds execute your code against real tests, and the score reflects what ran, not what looked plausible. You also talk through your approach out loud, the way the real round expects.
Do you cover system design rounds?+
Yes, as spoken rounds. Design rounds at Google, Meta, Amazon, and Stripe are mapped from reported questions, and you talk the design through the way you would at a whiteboard.
Where do the questions come from?+
Reported interview experiences and the companies’ own hiring pages, kept with sources. When your mock starts, the interview itself is generated for your resume and the job, so no two runs are identical.
What does it cost?+
Every interview is free. You pay only if you want the full scored feedback afterward.
