Answer Example

I evaluate performance and reliability by designing stress tests under extreme conditions, such as high temperatures and radiation exposure. For example, I tested a new power MOSFET by subjecting it to thermal cycling and monitored failure rates using Weibull analysis. I also used TCAD simulations to predict performance under these conditions, ensuring the device met reliability standards.
