Adobe interview questions

Very weird. I apply for Design Manager position for Adobe Stock. Went through several phone interviews with recruiter and hiring manager. Finally was invited onsite. After onsite, I got no response. Like, complete ignoring. Sent an email for the hiring manager and recruiter. Got no answer as well. I heard some companies are not giving detailed feedback, but not telling the decision is a completely new level of non-professionalism. Especially, after both Adobe and me invested a lot of time into the process.
