Unprofessional, extremely disrespectful interview process. I applied to the research scientist position in the Human-Computer Interaction team. The process started in May, and after two 45min technical screens I was asked to do 7 more interviews, including a research talk. The recruiters were unresponsive for a couple of weeks until I emailed the hiring manager, who pressed the recruiter to schedule the interviews. During the whole process, the recruiters were atrocious. The technical interviews were great. I was presented with research problems they are actually trying to solve and we brainstormed solutions together. They are all very smart and nice. I was left with a great impression of the team. Then after these 9 interviews they ghosted me. Yes, after more than 3 months of emails, interviews, and lots of preparation, they could not bother to send an email informing I wasn't selected. I first tried to follow up with the recruiter to no avail. Then I emailed the hiring manager, who seems like a decent person, and to my surprise they never replied. I was shocked as I never heard of this happening in our research community. Absolutely demoralizing.
