Docplexus Online Services Frontend Developer interview questions

Interview Process was fine and very logical. 1) First there was telephonic technical discussion about javascript,css and angular 2) They gave me an assignment in Angular,which i completed on time 3) Then I had a skype discussion with two of their product leads, which was fine discussion about their product and how can i contribute to improve and talked about what other things I know apart of front end stuff. The whole process was good and the CEO's attitude was also very positive,they cleared me what kind of things they are looking in a candidate but I was disappointed with the Hr person. When I cleared the technical rounds. He told me that my selection is almost sure,I just have to wait for some days.So I stopped interviewing to other companies. but after that he never get back to me even I sent the mail to him.He did not bother to inform me that they have chosen other candidate after wasting so much of my time.
