RBC Senior Test Automation Engineer At RBC Enterprise Information Management interview questions

I applied online for the position of Senior Test Automation Engineer and was called for the F2F interview last month. Unfortunately, I had very unpleasant experience at the interview. It was very insulting to say the least. Though the manager was very polite and welcoming, the technical interviewers came across as very unprofessional. After answering their questions, they are looking at each other and laughing, sarcastically smiling and had doubtful expressions on their face throughout. It really shows their work ethics and how they treat their employees. I never experienced such an unprofessional attitude in my 7 years of career working for top multinational companies. Think twice before applying to this department
