Going through a recruiter, this went straight from talking to the recruiter into a technical interview. The recruiter vetted me for being a technical fit. One of my cultural questions includes explicitly asking if the interviewee would be performing data structure & algorithm questions using a tool such as leetcode, HackerRank, etc, or in general. I was explicitly informed that the technical interview would only reflect day to day activity and be a real world mobile project exercise. Jumping into the interview, a woman jumped on the call. I couldn't quite tell if I was in the correct call or waiting on someone else as she was dressed unprofessionally and frankly not that presentable in any professional environment/manner to the point where it caught me off guard. Her attitude was extraordinarily dry/bland to the point of discomfort. When it was understood that she was performing the interview, she started to kick off the project. Introducing myself, I attempted to verify this was not a data structure and algorithm interview and she acknowledged it wasn't. Then she proceeded to tell me to open up Xcode and provided me instructions. The instructions had me writing an application with an optimized modified form of the Fibonacci sequence calculations. At this point, I didn't know what to say because I validated and expressed that this would not be a culture fit for me if presented with this type of Q&A. Clearly, the interviewee didn't understand what a "data structure & algorithm" interview meant. Ultimately, I expressed my concerns and discomfort, and she worked with me to move past this portion of the interview. Ultimately, it was an unsettling aura from her professionalism, tone, and the sheer poor communication going into the interview of expectations. It was clearly not a "culture fit".
