US Software Group interview questions

Worst interview experience ever, The interview was scheduled at 10:30, the first round started by 4 Pm. The first round was written and despite answering all the questions correctly was asked to leave. I checked my answers after the round on Google, and they were correct. And the recruiter was so rude, when I raised an issue about the process, he started abusing , and said do whatever you want to including writing a review on Glassdoor. This was complete employee harassment.
