after 4 round of phone/panel interview, they asked for an onsite interview and fly for that in the middle of pandemic. And then they ghosted. No proper feedback, just a system generated message.

Great process, start to finish. Informative and personal pre screen and preliminary interview process. On site interview was very professional, each interviewer was as concernced about answering my questions as they were asking questions of me. Left interview feeling very positive about the company and the direction they were heading and that I could be a fit in their organization. Rare that you get the full picture from a 3-4 hour interview process, but they nailed it. Follow up was excellent as well, was contacted within a few days to thank me for visiting and if I had any further questions. The decision making process was as timely.
