Scarred For Life

I have been working in the workforce for 11 years now outside of college. I just had my first 6.5 hour interview. It was 6.5 hours straight, although there was a lunch I was still being interviewed. I met 13 different people within that time frame, over 8 scheduled interviews throughout the day, many interviews having 3 people at a time. This was my dream job. I am scarred for life though, because it was so draining, so exhausting, challenging, and stressful. I cracked under the pressure at one point and was so stressed I peed myself a little. Like, a need a therapist after what happened. I work in HR, how the heck is this ok to do to people?
