Solicité el puesto a través de una agencia de empleo. Acudí a una entrevista en Instacart (San Francisco, CA) en mar 2018
Entrevista
Was introduced via a headhunter company to a recruiter at their company. Spoke to the recruiter who was extremely passionate about the company. Was told that I would be given a HackerRank assessment to do and was given the choice of Java or Python. The actual HackerRank assessment was a horrible experience, I was not told that I would need my own functioning development environment and that I would have to upload a full Java project. I only figured this out after starting the 1 hour test on HackerRank and saw that they were expecting a java project to be uploaded. Wasted 15 minutes trying to set up an environment, 15 minutes trying to understand the extremely long problem statement, leaving me half the time to try to implement a solution. Ridiculously long problem for a one hour time slot and not enough information about what is expected going in.

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.
Four long rounds and ghosted after the interview, even though all technical assessments went well. Tedious process but they do give you a gift card as a compensation for your time and effort.

2 rounds of 60 min coding sessions, a 1hr break after that, 45 min behavioural round, and then an easy system design round for 60 mins. Questions were pretty straight forward and easy. Second coding round has data structures involved, first one is just parsing thru dictionaries. Could not finish the second part of the second coding round. Behavioural interviewer has a dull personality and sort of killed the vibe. Otherwise I did really well on every round but still didn’t get the offer. Looking at Reddit, seems like many people had the same experience and were surprised to not get the offer so I don’t know if it’s worth your time interviewing here.
