CustomerXPs Software Developer interview questions

This was my worst experience of attending an interview. I reached there on time. And kept waiting for the HR to pick me from outside. As soon as I entered they handed a bundle of sheets with questions to be solved. Felt like I was attending a college examination. They gave one hour to write it. The interviewer entered the meeting room after 1 hour asked me if I finished the test. I told him I was not able to solve 2 algo questions. He just said I will be back in 5min.. n disappeared. After that one girl came took my bundle on answer sheet . And said HR will get back. I thought HR will come and kept waiting. I waited for sometime. Went out then they r telling we told you to leave rite why are you waiting. I felt the entire process was humiliating. They were just bothered with the 2 questions I didn't solve. And forgot about the entire bundle of questions I took trouble to answer. They should atleast have the decency to talk to a candidate for 5min if they r calling for an interview to understand the person. I am just wondering if the conduct in the interview is so pathetic ,how they r treating thier employees.

first we have the ppt of the company which was then followed by a pretty easy written test which had basic programming questions and has to write codes for two out of three problem statements followed by three technical interviews pretty simple
