J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez Instacart
Entretien
There's 1 recruiter screen (about 15 mins), 1 case interview (a metric shifted, what are the possible causes -- 30 mins), 1 case interview about analyzing an experiment 30 mins), 1 take home (expected to be about 5 hours, but you have a total of 30 to complete once you start it) that covers an experiment.
Final round is about 4 hours.
The process moved along fairly quickly for the most part.
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.

Entretien
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.

Question 1
Suppose we wanted to launch 15-minute deliveries in a specific area where we already deliver. How would you statistically test the results?
