First Republic Quantitative Analyst interview questions

The interviewer asked different kinds of questions, including statistical cumputing languages, such as R and Python, basic statistics knowledge, such as the assumptions of linear model, some easy SQL questions, such as the left join and wildcards. The most difficult part is about the project experience you have, you must be really really familiar with every detail of the projects you have done, like he asked how to calculate the value of VIF though the core of that project is regarding the principle component analysis. In fact, that was the hardest technical interview i have experienced. Good luck, guys

Three people from the team interviewed me. The team is pretty new. First they asked me to walk through my resume. And then many technical questions were asked related to my project or the position, focused on logistic regression, cross validation, assumptions of linear regression, etc. They asked me to write some SQL code. And very specific questions to see how you deal with data.
