Texas Instruments Student Program Employee- Product Engineer interview questions

Spoke to a recruiter at my University, and applied for the job. A few days later a hiring manager called me and told me to apply for a different job. After that, took a bit of scheduling but I was able to get an Webx interview with two current PE's. I shared a 10 minute presentation on myself with them, then they asked questions about the presentation. Nothing too technical until the end, when one interviewer showed me some technology he was working with and he asked me for some potiential points of failure on the product.
