Texas Instruments Product Marketing Engineer interview questions

I got a mail telling me that I've been selected for a video interview. I clicked on the said link and there were 5 questions that appeared on the screen. I just had to record my answers and send them. Then a few days later I got a call saying that I'd been moved to the next round in which I'd have a live video interview with one of the hiring managers. I replied with my available time slots. But then I did not receive any reply for a week. I called up the manager, and she said that they were not done interviewing all candidates, and I'd be informed soon. Some 8 days later, I get a regret mail informing me that they could not take me to the next round. The manager hasn't replied since then.
