Indeed Software Developer Engineer interview questions

The interview happened on the next day of job fair. There were two interviewers, and each have 20 min to ask you. The questions are all about strings. I think it was pretty easy but I kinda screwed up. Got rejected in 3 weeks.

This made me pretty angry....this happened to me and my friend who interviewed for full time 2 weeks ago. The HR told us that we would find out if we got the position the afternoon of the interview...her words were "we are a website that helps people find jobs so we know what it is like when you have to wait to find out if you got the job or not, so we will get back to everyone by the afternoon." I never got a response from them, I had to email them and 3 days later they emailed me back saying "sorry etc..." Same thing happend to my friend except they never got back to him.
