About Preptin

Interview prep system

The intelligence layer for coding interview prep.

Preptin sits on top of the platforms where candidates already solve. We capture submissions, diagnose weak patterns, schedule revision, recommend next practice, and turn progress into a readiness story.

Core idea

Submission intelligence

Retention

Revision loop

Consistency

Focused practice

Proof

Readiness profile

Prep Challenge

Focused practice based on readiness, weak topics, target company, and prior progress.

Revision system

Submissions become review signals, so practice returns before weak concepts fade.

Submission-backed tracking

Attempts, verdicts, states, and revision history create a more honest readiness picture than a streak counter alone.

How Preptin works today

One system across submission capture, weak-pattern diagnosis, revision, recommendations, and proof.

Step 1

Start from your current readiness

Open problems, continue a prep challenge, or follow a roadmap based on the gap you want to close next.

Step 2

Capture real submission signals

Every problem attempt and accepted submission adds context to your tracking, analytics, readiness, and activity.

Step 3

Diagnose and revisit weak patterns

Notes, mastery signals, and revision plans help you return to the concepts that matter before interviews.

Step 4

Turn progress into proof

Dashboard, readiness, public profile, and topic signals all roll up from the same underlying prep data.

What we believe

Better prep comes from tighter feedback loops, not just more volume.

Readiness matters more than raw solved counts

Personalized practice beats generic challenge feeds

A clean feedback loop reduces decision fatigue

Visible proof builds confidence before interviews
