HCLTech Software Developer interview questions

I was called for the interview but have to wait for 5 hours for interview. Interviewer took 1 hour per candidate but when he realized that his office time about to over, he started taking interview at 5 min per candidate. Initially he asked me about myself and what I have done. Then basic questions but didn't give me 1 min to recall the answer for the question. According to him I should have idea about the question what he was going to ask me and must have prepared for that. He was so hurry to complete the interview. If it was so then why initially he took 1 hour per candidate ? Worst interview I have ever had.
