Me postulé a través de una recomendación de un empleado. El proceso tomó 4 semanas. Acudí a una entrevista en Walmart
Entrevista
1st round: technical interview, other than below questions, there are also Coding+SQL questions
2nd round: behavioral questions: describe some of your projects, etc.
Not sure whether there will be a 3rd round or not
Preguntas de entrevista [1]
Pregunta 1
Describe what is DBSCAN algorithm?
what is ROC curve? what is confusion matrix? Bagging and Boosting?
It was not that bad, 3 initial rounds overall okay, it would have been nice if they added some more depth in questions and asked good questions.
and it would have been great if they call or tell something before interview.
A former colleague referred me to the data scientist position, and I was excited to dive in. The interview process was intense, starting with a phone screen that led to a technical round focused on SQL and experiment design. I was asked to write a complex SQL query and design an experiment for a forecasting model. Lucky timing — I had reviewed similar questions on prachub.com during my prep, which really helped boost my confidence. After a final behavioral round, I received an offer and happily accepted.
