Incedo Business Analyst interview questions

Did a big mistake by giving interview for this company. Phone interview followed by in-person interview. Phone interview was for 30 minutes. Later I was asked to come for an in-person interview saying that they need someone urgently. I had to fly all the way from other state to the office of Incedo in Iselin, New Jersey on my own expense. Had my interview with the VP and Business Analyst. The interview went good and was told that I will be updated by end of that week. I received no update from the company or from the recruiter of Incedo although I emailed them for any update. The only response I got was we will update by end of this week and this went on for a month. If it was a reject at least update the candidate. This is not the way a company should treat someone who comes for an interview. Stay away guys!!!!
