About Preptin
Interview prep system
Turn your code into understanding.
We are building a prep system around the real loop candidates need: solve, reflect, review, and come back stronger. Preptin connects problems, submissions, revision, prep challenge, and profile proof into one place so your progress tells a clearer story over time.
Core idea
Personalized prep
Retention
Notes + revision
Consistency
Challenge + streaks
Proof
Profile + analytics
Prep Challenge
A personalized active challenge based on your readiness, weak topics, target company, and prior progress.
Revision system
Problems turn into a review loop, so practice compounds instead of fading right after you solve.
Submission-backed tracking
Your submissions, states, and revision history create a more honest picture than a streak counter alone.
How Preptin works today
One system across daily practice, retention, and proof of growth.
Step 1
Practice from the right starting point
Open problems, continue your prep challenge, or follow a roadmap based on the area you want to improve next.
Step 2
Build a real submission history
Every problem attempt and accepted submission adds signal to your tracking, analytics, and activity.
Step 3
Turn practice into familiarity
Notes, mastery, and revision plans help you revisit the patterns that matter before interviews.
Step 4
See the story across the product
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.
Retention matters more than one-time solves
Personalized practice beats generic challenge feeds
A clean system reduces decision fatigue
Visible progress builds confidence before interviews
Built by a developer
Preptin is being shaped by the same frustrations most candidates feel while preparing.
Himanshu Gautam
Founder, Preptin
The product started from a simple observation: candidates often do the work, but the system around that work is fragmented. Problems live in one place, submissions in another, revision nowhere consistent, and progress is hard to trust. Preptin exists to bring that loop together.
