Every developer preparing for Big Tech interviews knows the drill: grind LeetCode, keep streaks alive, chase ratings, repeat.
But here’s the catch—most of us fail not because we lack knowledge, but because we lose rhythm.
The human brain doesn’t thrive in endless grind; it thrives in cycles, stories, and meaning.
The Hidden Problem Nobody Talks About
When I was preparing for interviews, I realized something odd.
I knew concepts, but I would often forget them when I needed them most.
Why?
- It wasn’t about memory. It was about energy.
- It wasn’t about discipline. It was about psychology.
Think about it—human physiology is wired for reward loops:
- Dopamine spikes when we see progress.
- Serotonin stabilizes when we have a routine.
- Cortisol rises when we’re stressed.
Traditional DSA prep ignores this completely. It reduces coding to a checklist instead of a journey.
And that’s why many of us burn out before we even reach the interview table.
The Spark That Led to AlgoPet
Even after discovering spaced repetition to fight forgetting, I realized there was still another battle—consistency.
Traditional DSA prep punishes you:
- Miss a streak → feel guilty
- Skip a day → feel like you’re behind
But that’s not how human psychology works.
Our physiology is wired for reward loops:
- Dopamine when we see progress
- Serotonin when we follow routines
- Cortisol when we’re stressed
So I asked myself: What if prep worked with this instead of against it?
That’s when the idea of AlgoPet came alive—not just as an app, but as a metaphor.
I imagined DSA prep as raising a companion:
- Every problem I solved fed it.
- Every review strengthened it.
- If I missed a day, it adapted instead of dying.
But there was another challenge: forgetting patterns.
Human memory fades unless refreshed. The Japanese technique shows that if you revisit something after 1, 3, 5, 7, 15, and 30 days, your brain locks it in for life.
So AlgoPet doesn’t just track streaks—it revives problems at the right intervals, fighting forgetting curves.
Every review isn’t just practice—it’s reinforcement.
What Changed for Me
Once I combined these two shifts—spaced repetition + growth mindset—everything changed:
- Forgetting patterns stopped being scary.
- I no longer obsessed over streak guilt.
- Confidence built naturally, because I wasn’t relearning—I was reinforcing.
- Consistency felt like momentum, not discipline.
Why This Matters
If you’re aiming for Big Tech, remember: you’re not just coding—you’re rewiring your brain.
- DSA is a marathon, not a sprint.
- Consistency beats intensity.
- Meaning beats mechanics.
- Memory can be trained—with the right rhythm.
The biggest prep problem isn’t algorithms—it’s how we, as humans, experience the journey.
The Takeaway
The truth is: you don’t fail DSA prep because you’re not smart enough or disciplined enough.
You fail because you’ve been prepping in a way that fights your brain instead of working with it.
The moment you align with human psychology—spaced repetition, feedback loops, growth instead of punishment—you unlock your true potential.
That’s how you walk into interviews:
- Not drained, but confident.
- Not fearing patterns, but recognizing them instantly.
