I applied online. The process took 3 weeks. I interviewed at Instacart (San Francisco, CA) in Feb 2018
Interview
Code challenge, hiring manager scan and then onsite.
The HRs are very professional, but the interviewers are expecting you to know their business very well and they give very vague questions without enough explanation, without any guidance. There would be three technical white boarding rounds, each rounds you will deal with two data scientists. They ask questions about the business is dealing with, but no guidance, and they explain things really poorly, even one of them didn't say a word during the whole 45 min session.??????? Excuse me????
And they will tell you the result immediately, if you don't pass, all the following interviews will be cancelled.
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.
