Smart Robot Episode Dataloader

Problem: Robot datasets have wildly variable episode lengths (10 seconds to 5+ minutes), causing massive load imbalance in distributed training. Worker 1 might process 50 short episodes while Worker 2 gets stuck on 3 long cooking demos.

Solution: Content-aware sharding that balances total compute workload, not episode count.

What happens in a ML Interview?

• Background and culture fit
• Whiteboard Coding (similar to SWE interviews)
• Pair Coding (similar to SWE-interviews)
• Pair debugging (often ML-specific code)
• Math puzzles (e.g. involving Linear Algebra)
• Take-home ML project
• Applied ML (e.g. explain how you'd solve this problem with ML)
• Previous ML projects (e.g. probing on what you tried, why things did/didn't work)
• ML Theory (e.g. bias-variance tradeoff, overfitting, underfitting, understanding of specific algorithms)

# Vanilla Crew Scheduling

# Step 1: Define the flights and crew members, along with the flight times and max work hours.

# Flight times in hours
flight_times = {
    "flight_1": 5,
    "flight_2": 3,
    "flight_3": 4,
}
