Is it a big deal to not finish by timer's end on Hirevue? Am I finished?

I recently completed a Hirevue interview for a BB. I believe my responses were articulate; I maintained eye contact through the webcam, had good posture, answered the questions effectively, and projected confidence. However, there was one significant issue: I didn't finish my responses for the last two questions within the two-minute time limit. For the third question, it wasn't much of a concern as I was nearly done and only missed the concluding sentence. The question was along the lines of "tell me about a time when you’ve had to go above and beyond to help a customer/client/teammate?", and at the end I managed to say, "In relation to the [POSITION] role at bb, this experience underlines my proficiency in identifying and evaluating investment opportunities..." but couldn't finish the rest of the sentence ("..., leveraging various information sources, and initiating strategic business relationships.) before the timer ran out. I'm not sure how obvious it was that I wasn't finished at the timer's end, but I covered all my points.

The second question posed a bigger problem. I focused on looking into the camera and sounding authentic and got carried away with my response, losing track of the timer. When I finished, I realized that the time had elapsed much earlier, and it was apparent that I hadn’t completed my answer. I think the timer ended when I was 75% through my response, which means it will be obvious that I wasn't paying attention to the timer and failed to finish my response. 

Given that all of the other aspects of my responses were strong, do I still stand a chance? Is exceeding the time limit and being cut off a major issue in Hirevue interviews, or should I remain hopeful about my prospects? Should I forget about getting an offer with this firm? This was my first experience with a Hirevue interview. Thank you for your time and consideration.
