Intellect Design Arena Performance Test Engineer interview questions

Worst experience of interview process I came across in my till date IT career. I reached to venue at schedule time and waited for 6 hours for first round of interview. and Still HR guys said to wait for 1 more hour. Being a HR person If you can not manage the schedule interview candidate , PLEASE SHUT DOWN your company door. Dont take exam of someone's patience. There were many guys who has faced the same situation, I encourage all to share their experience.
