Texas Instruments Technical Sales Engineering Rotation Program interview questions

Started at the on-campus career fair, where I approached TI's booth and spoke with a rep in tech sales. After discussing my interest and qualifications, I was informed of their interest to do on on-site 30 minute interview a few hours later. When I returned for the interview I was asked a variety of behavioral questions, with a lot of "describe a time when/where you" questions, specifically with questions such as "failed" "encourtered hardship" "had a co-worker not contributing" as well as "describe how a transistor works to us if we were joe-schmoes." After this interview, I was told I would be contacted if they wanted to continue the process. I was then contacted two weeks later via email & phone, and was directed to an online interview process to be completed in the next 48 hours. I then went online and was asked 6 questions, 5 about specific times where I encountered some sort of relationship-based hardship or success. Heavy emphasis on "Talk about a specific time". After that, I was contacted for an interview with a hiring manager, scheduled for one hour. He wasn't too friendly and really emphasized technical aptitude, whereas the prior interview emphasized more behavioral. I struggled with pulling out specific incidences he was looking for. Questions included tell me a time you had a problem in a relationship with someone and how it came out, tell me a time where you did something very challenging, tell me a time where you had no answers but had to make a decision.
