screening with recruiter, 30 min interview with hiring manager, data challenge and sql challenge. I withdrew after the third round since I accepted an offer elsewhere.
I was quite disappointed at the challenge round and knew then that I would not want to join instacart because it seemed to me that the company is looking for people who already fit their clear-cut mold; they are not looking for entrepreneurial people, people who build new stuff. They are looking for people who are really good at doing what they are told to do. They are not looking for explorers or builders. Also, the fact that they still use powerpoint slides to communicate was a huge minus for me.
Also, the interviews were often postponed by weeks, sometimes last minute.
