Varian Medical Systems Software Engineer III interview questions

Whole recruiting process is super slow. It took them ~2months for the recruiter to schedule an interview. The panel interview was little confusing. Not sure what they were looking for. Asked questions about my experience and they described the job duties. It was almost 95% match to the my work experience. Then asked me to write pseudo code for a simple problem. Didn't even give me an opportunity to complete, in 5 mins the interviewer interrupted and swifted to the next question. Although, I have asked clarifying questions and completed more than half of the pseudo code. It was a very simple question. Randomly asked me some questions which didn't make any sense, looked like they wanted to pass some time. This shows their unpreparedness.
