Texas Instruments Applications Engineer interview questions

They contacted me several weeks after my universities job fair. I had a pleasant face to face interview on campus and at the end he told me I should hear back in two weeks. That interview was not very technical but rather about my interests and schoolwork. I instead heard back a month later that I got to the second round of interviews. They said it would be a technical video interview on their own video conferencing system. Two whole months after I got the email that i moved to the next round they finally scheduled a time for the video interview after many unsuccessful attempts on their end. This interview was completely behavioral after telling me that it would be technical. They asked a lot about the teams and projects that I worked on. They also asked me to explain the process we used to collect data in one of my projects. I was not happy that they took so long to schedule the interview but only hours after my interview sent me an email that I did not get the position.
