How it works

01
📅

Book a session

Choose a time slot and pick your focus — LeetCode Hard, system design, or a mix. We match you with a senior engineer who knows your weak spots.

02
🦀

Get paired

You're matched with a vetted senior Rust engineer — someone who has shipped production Rust and aced Big-Tech interviews. They prep for your session.

03

Solve it live

Share your screen. Write real Rust together. Your engineer guides you through idioms, ownership patterns, and optimal complexity — no hand-waving.

What you'll
actually solve

Not toy examples. Not watered-down walkthroughs. You'll work through the exact problems top companies use to screen for senior IC roles — implemented correctly in Rust.

  • LeetCode Hard (graphs, DP, heaps, tries)
  • Distributed systems design
  • Rust ownership & lifetime patterns
  • Async I/O with Tokio
  • Low-latency data structures
  • Mock FAANG-style interviews
trapping_rain_water.rs
fn trap(height: Vec<i32>) -> i32 {
    let (mut left, mut right) = (0, height.len() - 1);
    let (mut lmax, mut rmax) = (0, 0);
    let mut water = 0;

    while left < right {
        if height[left] < height[right] {
            if height[left] >= lmax {
                lmax = height[left];
            } else {
                water += lmax - height[left];
            }
            left += 1;
        } else {
            if height[right] >= rmax {
                rmax = height[right];
            } else {
                water += rmax - height[right];
            }
            right -= 1;
        }
    }
    water  // O(n) time, O(1) space
}
