I applied online. The process took 3 weeks.

I had a couple of interview rounds with Instacart. Overall, I think it went pretty well, except for one round that didn't feel as strong. I asked for feedback afterward, but unfortunately they didn't share any. The system design and algorithm questions were manageable, especially if you're familiar with LeetCode-style problems. One thing I really appreciated is that they clearly explain what to expect in each interview round ahead of time, which helps a lot with preparation.

One of the rounds was behavioral. They asked questions based on my resume and also about how I work and behave in a team environment.
