Don't interview them. It's a sinking ship; people are leaving internally and just keeping an open position to maintain a positive image. They took 4 rounds and the feedback was positive. Everyone took an interview from their phone standing in a crowded place outside the office(even the last interview by CPO). Later HR said we were restructuring and would come back to me later and now ghosting over mail and calls. They don't even have the professional courtesy to mail candidates about results. They are just looking to waste candidates' time, please don't interview and if you call to offer don't join. They don't even have the autonomy to build something better than their offline business.
