Texas Instruments Embedded Software Developer interview questions

Written test followed consisting of math and cs concepts mcqs followrd by technical interview and then an informla call from the HR about future plans and work culture at texas instruments

First two rounds of interactions were good and I moved to the third round of interview. The interviewer had no clue as to how many rounds of interview they were gonna put me through. When I asked during the third interview, he told me that he would make me talk to their clients to see how i do in real world scenarios(felt really wierd). Well that was the last time i heard of these guys. Never called me back and never sent any feedback about the next steps. Felt like I had wasted my team interviewing with them. It would be appreciated if TI team atleast had the courtesy to inform if they were going with a different candidate.
