IBM Software Application Developer interview questions

Ibm took my 2 interview round .one is techical and other is PMO round. In PMO round they discussed salary and all. On second day my documentation and background verification done. I was waiting till almost 1 month for offer. Again tried to connect with recruiters and they send me one mail that no going to ahead with your candidature not received required approvals. West of my lots of time...getting acknowledged only after i tried to connect with them.. Bad experience. Don't west your time on this type of interview.

Only one interview for both technical and HR round. Around 1 hour. Interviewer asked about techs mentioned in my resume. And my final year project. All questions were from resume
