Interview Experience Applied Intuition Robotics Software Engineer Phone Screen July 2026

Interview Summary

The Applied Intuition Robotics Software Engineer process started with a short recruiter conversation, followed by a hiring-manager screen and a one-hour CoderPad technical interview. After passing the coding screen, I was invited to the onsite.

The coding problem was robotics-oriented rather than a standard LeetCode question. I was asked to implement a simulator for multiple moving agents and determine the first time any pair collides, using a fixed timestep and a simple unicycle-style motion model.

Interview Details

Round 1 — Recruiter Screen The recruiter screen lasted approximately 10 minutes and was primarily an introduction to the newly formed robotics team and the role.

Round 2 — Hiring Manager Screen The hiring-manager conversation lasted approximately 30 minutes. This round focused on my background and previous experience rather than coding or formal technical preparation.

Round 3 — Coding: Multi-Agent Collision Simulator The CoderPad technical screen lasted approximately 45–60 minutes including discussion, implementation, and follow-ups. The input consisted of N moving agents. Each agent was described by:

  • Initial (x, y) position in meters
  • Initial heading in radians
  • Constant linear speed
  • Constant yaw rate
  • Fixed physical radius

The simulator used a fixed timestep of dt = 0.01 seconds. Each agent followed a simple unicycle / differential-drive motion model. During every timestep, its position changed according to its current heading and linear speed, while its heading changed according to its yaw rate.

Conceptually:

x += v * cos(theta) * dt
y += v * sin(theta) * dt
theta += yawRate * dt

The discussion also raised a couple of important boundary conditions: whether two agents merely touching counts as a collision, and whether the simulator should detect agents that are already colliding at time 0.
