IBM Software Engineer interview questions

I applied online when the job was recently posted and cleared the initial screening. I received the invitation for IPAT test, which I gave the very next day when I received the invitation email. Ever since that day, the job application status was shown as "Interviews". I have been following up with the recruiter ever since that day which she never responded. After few days, I had to call IBM for the followup. They told me to email my concerns to IBM Opportunities Support which I did. After two days, I receive an email from the recruiter saying that this position has been filled. It hurts to see a company like IBM, shows such negligence.

Scheduled an interview and went in the following week. There were 2 interviewers, one was the hiring manager and was nice. The other interviewer was condescending and did not give off a good impression throughout the interview.
