Thermo Fisher Scientific Sr. Software Engineer interview questions

There were 2 rounds of interview online technical interview and a techno-manager. Technical interview panel had 2 people one from India and another from China They initially started with Java Basics then Springs, Springboot concepts later on spring transactions and message brokers concepts. It went for 1.5 hr session. Manager round was for an half an hour with the below question 1. Where you do wanna see yourself in next 5 years. 2. What are the technical challenges faced in your career. 3. How do you handle a team. etc.

Had a phone interview with hiring Manager who did not even know how to ask questions. He gave a scenario and asked to give a solution. By the time, I could comprehend his long scenario, he says "Forget it, here is another scenario". Again he says "Forget it". The interviewer lacked interview ethics and closed the call by asking me if I really worked on them or not. Most unprofessional interview I have ever seen. Also the recruiter did not even bother to answer back when asked for feedback (out of curiosity of course for this lost cause)
