Thinkanalytics Senior Software Engineer interview questions

As per the job description they had mentioned that to be up for the holistic picture as this is a start up.interview was scheduled and at last moment they cancelled it and scheduled a week after - unprofessionalism (you should atleast value the time if people turning up for such instances, we are really working hard for it!) Honestly the interview went all ok infact above my expectations. Answered all questions in apt way but couldn't go through. Not sure what went wrong, they have not given in the feedback apart from that they have enjoyed the whole interview process and panel was impressed. But still I didn't made through. Please have the courtesy to atleast share the actual feedback as it brings the moral down of a person.
