Veritas Technologies interview questions

I was invited to be interviewed for a Manager position. When I arrived the position I was invited for, was not the position the person wanted to interview me for. She interviewed me for a Sales position. I thought this is very disrespectful to invite a candidate for an specific position to then telling him they don´t see a fit for that role but another role. Could have saved time and money as I was not reimbursed for me travel costs. Also never got feedback from them. This interview was a joke!

Interview is related to the work that is performed and basic functionalities over there. Basically the questions relate to understand what is your learning and how do you apply the learning ?
