J'ai postulé via un recruteur. Le processus a pris 2 mois. J'ai passé un entretien chez Instacart en août 2024
Entretien
Reached out by recruiter. First round is OA, which has 4 questions in 45 mins. Solved 3 out of 4. (1 easy, 2 medium, 1 medium-hard). Got to the second round, it's 1 hour coding interview with one of their engineers. Questions are not hard but time consuming (read file, string processing......). There were 2 follow up questions, also have to solve everything in 45 mins (15 mins is for introduction & QA). I think it's not really possible to finish everything because they also ask you how to improve the performance. I feel interviewer was not really familiar with the questions so it took him a while to understand. Got the rejection because they said they are looking for more Java fundamentals work and in depth SQL. Funny thing is I did not get any SQL questions......
Overall it's a disorganized interview process.
I'm sure it's easier to grade applicants with AI, but it'd be nice to have humans involved in the interview process, too. You'll face a couple of AI powered coding challenges. The bigger problems are the ethical implications here after looking into how the company works, with variable pricing based on data on how badly they can screw the consumer with upcharges and how to keep money in their pockets rather than the shoppers & drivers

First there is a codesignal test. This is for 90 minutes and felt frantic. Way too many features/code paths to implement.
Then there is the karat llm interview which is 50 minutes.
Then a full day of regular interview loop.

Question 1
For CodeSignal it was implementing a cache key store with timestamps. Started with basic setting and getting, then evolved into more advanced code. 4 different parts. Writing a lot of code for this.
For the LLM interview you work with a company called Karat. You are giving an VS code like workspace and an ai to help. You have 50 minutes. They then dump a large project in your space. For me it was a bus route simulator.
I was then asked to implement a feature : Have the system prioritize Priority Pass people. I used the LLM to track down the code and implement it, but it was difficult to test in code that is unknown to me. The next feature was implementing wheelchairs for the bus which requires special capacity checks.

1. Online OA with codesignal to start with. Very standard and not hard
2. Got the 4 interview rounds and you can always divide into 2 parts of 2 interviews each. It was be 2 codesignals with medium difficulty and I managed to do both. One system design which was average for me and interviewer was okay as well. Behavioural round was standard. No wonder why I didn't manage to get the offer.
