I had a screen with a manager and then a technical interview with two current data scientists writing in r on the platform coder pad. While trying and thinking out loud, there was a snicker in the interview room. I was derailed from the task and felt the need to call it out. The laugh was denied by the interviewer who went further to say everyone else had left the room at that point. At the end of the call multiple people spoke saying goodbye which leads me to believe the interview covered for a colleague who mocked me. I withdrew my application immediately after.
