Red Hat India

I applied on their careers portal, recruiter reached out to me and scheduled the first round. The interview was scheduled for 15 minutes, it started with introductions and then interviewer was prepared to ask 3 questions and some follow up questions to these.

2 rounds of technical interviews. Didn't qualify for further process. It was a good conversation with the engineers. Revolved around system design and coding concepts. Discussed about current projects and design decision that were made.

I cleared the interview rounds for a Software Engineering role and was explicitly told by the recruiter that I was selected. We discussed compensation, agreed on a tentative start date, and when a system rejection email randomly triggered, HR told me in writing to ignore it as a system error. Relying on these confirmations, I turned down other active job opportunities. After 10days, my portal status was changed to "Declined." When I escalated this, management completely shifted the narrative, claiming the previous conversations were just "exploratory" and that the role was now closed. Red Hat’s internal team completely failed to align, and their recruiter directly misled me into destroying other career opportunities. To lead an engineer on to the point of discussing exact start dates and dismissing rejection notices, only to pull the rug out and deny it later, is a severe breach of professional ethics.
