Texas Instruments Internship interview questions

test, interview1, interview2, hr round. this interview is based on academic question. I enjoyed the interview. I have accepted the offer letter. now i am planning to get a PPO from the company and I wil try my best to get so.

I applied through my university. Three days after, I received an invitation thru text message and email to have an on-site interview with the finance head. Then two days after I had a phone interview with HR who initially invited me. They let you know the result after two to three weeks thru a text message.
