Orderchamp interview questions

I had to send my CV and Cover Letter. Then I got an interview with the HR, who told me the interview went very very very (x3) well. I received some homework to do as a technical assessment. As it was during the exam session, I completed the assessment after two days (took me some hours). Did not receive any message, and when I explicitly asked the HR they told me they still had to evaluate everything. I kept other Internship offers on hold for them and they knew. I was never contacted again even if I asked them to do it. This was all for an internship with no hiring chances after its completion. They gave me the impression they simply wanted to get everything done the fastest way possible, and I believe they chose the first person to send the assessment report back.
