Applied Medical Manufacturing Engineer interview questions

First call was with recruiter. Super nice and friendly. Said there would be 3-4 more rounds after this and set me up with a first round in person. Until the day of I had no idea how many people would be interviewing and who they were. Morning of my interview I'm told it will be 4 people in an interview plus a tour of the facility. Then it changed to 5 people in a panel interviewing me. In a first round interview I have never had more than 2 people let alone 5. For an entry level , 2 years experience required job, I've never had a panel discredit my prior work and be so disrespectful about it By far the most unprofessional interview process I've ever had.

I did only one phone interview, they ask basic questions that were not too difficult and no technical questions in the initial call.The interviewing lady seemed nice and interested but surprisingly I did not get contacted for a second round.
