Informatica Technical Support Engineer interview questions

I cleared 5 rounds of interview. All rounds lasted 1-1.5 hrs . Invested so much time and effort for this process. I also received a mail that I am shortlisted and shared all my documents with the recruiter. Its been 2 months haven't heard anything from anyone. No hr discussion happened and no offer letter given. The recruiter didn't reply to my mails and her phone was not reachable for 1 month. Later when I was luckily able to connect with her all she said was she'll keep me posted . Didn't get any update from her since then. Didn't expect such behaviour from such a well reputed organization. Someone should atleast give a closure if they are not going to send offer letter now. It's very frustrating when they keep us hanging. I remember the recruiter saying in the first call that all rounds will happen on the same day and I'll get my offer if selected by EOD . Let alone offer the interview rounds lasted for 2 weeks. Wish I wouldn't have wasted my time!

Process was long, drawn out, and in the end, I felt my time was wasted being hyped up, having a VP come in to meet me etc, all to end with no offer.
