Splunk Senior Frontend Engineer interview questions

I underwent a hiring process that spanned over a month and encompassed multiple stages. I engaged in two discussions with recruiters, one with a manager, and completed a home exercise. Additionally, I participated in pair programming with a Principal Engineer and a Senior Engineer, Collaboration 1 with a Principal Engineer and a Senior Engineer, Collaboration 2 with two Engineers, and Collaboration 3 with a Designer and a Product Manager. The process was progressing well until Collaboration 1, where unfortunately, one engineer was extremely rude. The individual wasn't interviewing me but, instead, was attempting to showcase their ego. It was evident that another colleague was uncomfortable throughout the interview due to the way the engineer conducted it. Although this person was the only negative experience throughout the process, I have never encountered someone so rude in my entire career. After completing all these stages, they ghosted.
