Questions posées lors d’un entretien d’embauche pour JavaScript Developer chez i-exceed technology solutions

Please dont waste your time going for an interview at i-exceed, I went there for an interview for javascript developer. First they took written example which was soo easy even a layman could answer it. Then after that it was a technical interview followed by another technical cum HR round which was taken by senior project manager. After everything they said "You are selected", but still they didn't send any confirmation or any positive response. I tried calling them also emailed 2-3 times but didn't get any response. I want to ask if you don't want to hire why do you waste others time, what benefit do you get by doing this??

I had an interview with I-Exceed on October 2016.The interview process includes first round of written test,two rounds of technical discussion,an HR Round and a VP round. I have cleared through all the rounds of interview and they said that they will roll out the offer letter within a day. But as other candidates said it was waste of time, They did not release the offer letter. They said that the profile is on hold without any reason. So beware of this company.It just waste your time, The worst experince i had ever. No value for the skills,experience and talent.Just Waste of time.
