CommerceIQ Software Development Engineer interview questions

Applied online. Called for the F2F interview. First round was coding test. They asked me whether to write on paper or laptop. I opted for laptop stupidly. A guy came to evaluate, He didn't look like a software engineer, he evaluated. I prepared those 3 questions 2 days before, I'm confident that I will go for next round, but surprisingly HR came and told 'Written test not cleared, you can apply after 3 months' and went. I thought of asking the feedback, she didn't even bother to give. No ethics, noting, creepy. I didn't see an HR with that ignorance.

One online coding challenge on hacker earth. Followed by 4 f2f interviews. Complete day was wasted. Later got to know no suitable position at this point of time. Bad really creepy process.
