Envié una solicitud electrónica. El proceso duró 2 semanas. Acudí a una entrevista en Instacart en jul 2021
Entrevista
Initial conversation with recruiter, then 45 minute case interview with a data scientist. Process seemed a bit disorganized, and the interviewer seemed totally disinterested in the interview (obviously working during interview and not engaged).

Pregunta 1
How would you analyze this experiment we conducted?
Faced a deep technical challenge during the interview, asked to design a personalization algorithm for product recommendations. I walked them through feature engineering and model choices, which stressed me out initially. Luckily, I realized the structure was almost identical to a problem I had explored on prachub.com while prepping. The interview progressed through a behavioral round where they focused on my previous experiences, and I ultimately received an offer, but decided to decline after careful consideration. Overall, it was intense but rewarding.
It was pretty straightforward. HR and then technicals. The technicals were a mix of statistics and math questions. Overall, it moved pretty quickly. My interviewer was quite late with no apology and in general not very friendly. I knew someone interviewing at the same time and they had a much better experience and recieved the same questions.
