Wackytoon Studio interview questions

The interview process was smooth but the following days where hell. 1st day of the interview was smooth and about 4-5 people took my interview and I was told we will call you for another round of technical skill check. A week went by and I got no response. I ended up following up with them and then I got a call asking me to come as soon as possible. 2nd day of the interview, I was given a bunch of excel and word tricks to do and was asked to write a small notice as a writing sample. After this there was a discussion about compensation. Well it was a negotiation. At the end of the interview I was told we will get back to you by the end of the week. 2 weeks went by no update, numerous calls and texts went answered and I gave up after that. The companies like these should know that when a candidate is investing so much time, they should also reciprocate. It is just a courtesy and nothing else to let candidates know their decision.
