Just wrapped up an interview process that started with an HR round, followed by a solid 1-hour technical discussion. The focus was heavily on battery design, so be prepared to dive into the fundamentals and formulas—especially around:
🔋 Battery architecture
⚡ Charge/discharge cycles
🧪 Electrochemistry basics
📐 Design parameters (energy density, C-rate, SoC, thermal considerations)
Some questions went into the mechanical design aspects too—things like shock & vibration testing, packaging, and cooling systems.
