OATSystems Applications Support Engineer interview questions

Interviewer has asked me different questions in Oracle SQL, PLSQL and Unix. Questions were ranging from simple, average and difficult. He had nicely framed the questions and gave enough time to write programs. But what I hate about this company is, they never reverted about result. I have answered almost all the questions, surely I would have cracked that round. Even in case, if I had not cracked, thats fine, but I expected the HR to get back to me and update the same which never happened even after couple of followup mails. Based on my understanding, this company is in its growing stage, if you don't show enough professionalism in your hiring activities, you wont be getting the best talents into your company anytime.
