HCLTech Technical Leader interview questions

Can you imagine a waiting period of 7 hours before you get called for your turn..it was thoroughly humiliating for a 8 years experienced to sit like that..... no process followed at all...when asked when will we get our turn ,one of the interviewer said that they were calling candidates by the time they came in....i came by 10 a.m and was called in for interview at 6.30 p.m...........i was asked to come by 10a.m,..its scheduled interview...got 2 reminder calls at 7.30 and 10 to chk if i am in ..But all that is left is my wasted 7 hrs....
