Welcome to your interview for the Software Engineer role at Sonatus.
The question is on your right: Longest Low-Variance Telemetry Window. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen. You have three graded attempts to score 7/10 or better.
Given an array of vehicle telemetry signals, find the longest contiguous subarray where the signal variance remains below a specific threshold.
