Me postulé a través de una recomendación de un empleado. El proceso tomó 2 semanas. Acudí a una entrevista en Wells Fargo en sept 2022
Entrevista
Included two rounds of technical interviews. Both of them started with general questions and got more difficult later on. Interviewers were looking for the topics that I had difficulty answering. Then they asked harder questions on those topics!

Pregunta 1
First round: Questions on my background. What is Linear Regression (LR), and why do we use it? What are LS assumptions? How do you address overfitting? What are the different methods of Regularization? Why is Collinearity not desired?
Second Round: Questions on my background. Why do more features lead to overfitting? What are other methods of Regularization? What are hyperparameters in Random Forest, XGBoost, and FF NN? What is the optimization formula of SVM? What are transformation methods in NLP, and explain the pros and cons of each of them? How do we evaluate a model? What are the pros and cons of cross-validation? What optimization algorithm do you suggest for a sparse matrix in classification?
I applied online and completed two interview rounds, including an in-person Superday in Charlotte on November 19. During the Superday, one interviewer asked several incorrect technical questions and initially disagreed with my answers, but the second interviewer disagreed with him and technically supported my responses.
After that, the first interviewer became largely disengaged and concluded by saying, “don’t be upset if you don’t get the offer.” Overall, the process felt uncoordinated. Although we were told decisions would be shared in early December, HR provided no follow-up or response afterward, effectively leaving candidates without closure.

Tough but fair interview, took about 2 weeks, first round phone interview with HR and second with head of team, asking more technical than behavioral questions. Started with talking through resume and then about different relevant topics.
