Interview
Wow the interview was just terrible. Never really experienced a bad interview until this. Thanks Daniel. It was part of the phone screening for the quant research team. The guy didn't really care about you as a person and really liked to nit-pick. Shoot straight into technical questions. He came into our online career fair (b/c covid) where we're scheduled to meet 10 minutes. During so, from the feedback I got my classmates, he asked technical questions during a career fair. What a great way to represent the firm or learn about it or even introduce themselves or try to pitch about us. The person I spoke to during career fair had a similar background to me and research experience. After hearing the experience about daniel from my classmates, I went into the interview thinking it was going to be similar structure. It was, but this is an interview which a few technical questions are fair game. He then proceeds to only focus on technical questions and likes to quiz you on quant concepts not on the resume. We only spoke briefly about the resume. We went over time and (he did asked is it okay we go over time) just to continue asking more technical questions. I felt that my background in my resume aligned with the role really well and it was suppose to be a screening, yet he just loves going into picking on quant concepts. But really what this guy did at the career sorta speaks to his character and why it was a bad interview experience. The concepts he asked also didn't directly relate to the role. Like VaR or etc. They were looking for ML and DS in finance to really communicated bloomberg clients trhough juypter notebooks.
