ASML Software Development Engineer In Test SDET interview questions

Process consisted of 6 total interviews. I personally went through 5 total interviews before my 6th interview was to be rescheduled while I was finishing up my 5th interview due to "urgent escalation". The recruiter said that they will be in touch, but never reached out to me. However, after a week, I saw my application was silently rejected on the online portal. I never received an rejection email, I just happened to check the status online one day. Following this, I emailed the recruiter once more and asked for feedback as I was surprised at the application result given my positive conversations with the multiple hiring managers in my first 5 interviews. Never got a reply to any of my emails. This was one of my dream companies, and I expected a higher level of professionalism. At the very least a rejection email from the main recruiter and some feedback, especially given the amount of time I dedicated to preparing for this interview process. If you are asking a candidate to participate in 6 interviews, I don't think that's an unreasonable expectation. Very disappointment by the interview process for this company.
