Interview Preparation Tips

Interview preparation tips for other job seekers - Horrible experience:
Totally three rounds of interview where their first two rounds are technical and third round was behaviour interview . The interview went well and they informed me that the result will be announced after 2 weeks of time.
But even after 1 month , I haven't gotten any feedback from them , but the job application status changed to "No longer under construction" in the company's website .They were not even bother to give feedback to the candidate.
Exxon Mobil Bangalore team requires a lot of improvement in the way they are treating candidates and their interviews are very sub standard and needs lot of improvement .
Most of the interviewers were Ex Reliance industries limited employees who run their Own lobby and denying the opportunities for better candidates due to insecurity....So Exxon Mobil Bangalore is in a pathetic situation.....
