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.
