I have been genuinely interested in AMD for years and still am. Completed 4 rounds of interviews for a Senior Staff AI/ML & GPU Performance Validation Engineer role. Invested significant time preparing for AMD-specific technologies and interview rounds. The hiring manager missed the first scheduled interview entirely. I followed up to request a reschedule and accommodated the change. Even though I had provided my availability a week in advance, I received an after 5 PM notification to interview the next day, and another round on the following day. I accommodated every last-minute change without complaint. The technical interviews themselves were excellent and engineers were knowledgeable and engaging. After completing all 4 rounds, the recruiter explicitly confirmed the hiring manager was 'still interested' and promised next steps 'very soon.' Then complete silence. I sent three professional follow-up emails over 4 weeks — zero response to any of them. I communicated a competing offer deadline clearly. Still nothing. A month later I checked the application portal myself and discovered my status had been quietly changed to 'not being considered' — just days after being told the manager was still interested. No rejection email, no phone call, no closure. I only found out because I manually checked the portal. The whole experience made me question whether I had actually interviewed at AMD or been scammed. Candidates who invest this level of time and effort deserve a 30-second rejection email at minimum. Advice to management: Build a structured candidate communication process. If the answer is no, say no. Don't leave final-round candidates checking a portal to find out their fate.
