IBM Software Engineer interview questions

I applied online after school event and they got back to me in 5 days. It was heavily focused on string parsings and regular expressions which I don't really like. Also, during the coding, the camera was turned on the whold time (which means it was turned on for almost 2 hours and half). I felt like I was supervised even though it was an online coding challenge. I prepared data structure part for the position, but while I was taking it, I realized that their interview questions were not testing what i am good at. So, I felt they don't fit into my career.
