TechSophy interview questions

There was one round scheduled which was called technical assessment , it was rescheduled for few times as the panel was not there. For the first round i was asked project related questions , some java coding question using like sort a list of employees by name etc. One sql query was also asked. I think i did pretty well and was hoping for next round. Got the rejection mail , i connected with HR to ask what was the feedback , so that i will work on it. Very strange answer that "There was no feedback, thanks , bye". I wasted my time on such a company that can't properly communicate with candidates. welp that's life.
