Questions posées lors d’un entretien d’embauche pour Staff Software Engineer - .NET/Java chez Visa Inc.

I went through their interview process, I was able to clear the initial coding assessment, medium standard 1 dynamic, 1 tricky array problem similar to Leetcode . I was prompt to the next round which is one-one coding assessment. I was asked all about Java and JavaScript. I asked my recruiter for details about the job requirement, make sure that they understand that I'm from .NET stack and had limited exposure to client side scripting like JavaScript and Angular. Also mentioned that I'm learning new technology stack like reactJs, reactNative and Angular. But all they ask about angular, Java and JavaScript. Today I have got an update from their recruiting team that they have filled out this position. My frustration is, I have been honest with them on the day 1, not sure why they dragged this up to 8 weeks ? Taking assessment needs practice and at least 1.5 hour of time to complete. It's complete waste of time, these client side technology is not rocket science, they can be learnt in few days.
