Ad Hoc (DC) Software Engineer interview questions

Waste of time, don't bother. did the first phone screen and was told to do some assignment that I would hear back after three days of doing it. I did it immediately and then never heard back, don't think they even bothered to look at it. After two weeks I sent a message to follow up and nothing. They will just waste your time and not even bother to look at the assignment. Just shoot down people before wasting their time with these assignment.
