Hitachi Vantara Full/Mean Stack Developer interview questions

I was interviewed for a senior NodeJS + Angular/React Full stack developer position. As I had experience with Angular so my interview was focused on Angular + Node. Though the recruiter told me that more will be Angular as I was little front-end heavy but both L1 (Core Technical) and L2 (Techno+Manager) were more focused on NodeJS though I had enough of basics knowledge so was able to answer almost 85% questions. After 2nd round, interviewer was pretty impressed and we were discussing how quickly I can learn the AWS as that was also a requirement for project. But after several followups with the recruiters I never got any feedback or any sort of response even I was following up till 2 days before my last working day. That was the worst part, even after first round I had to followup for feedback and setting up next round as I cleared L1.
