Saw a posting for a Rails Engineer position in a developer newsletter. Emailed my resumé and received a code challenge from Hackerrank. It was pretty simple and then had a call with an engineer, who asked me pretty standard questions about my background and why I was interested in Instacart. I then received a longer code challenge that involves building a Rails application. There were two parts to the challenge - one more frontend-focused and the other more backend, analytics-focused. It's certainly challenging and you need to be careful on which parts of the app you spend your time. After that, I was put in touch with a recruiter, who told me more about the company and scheduled a time for me to come to the office for an onsite. During the onsite, I did a pair programming challenge that was fairly simple. Then talked to their head of design, software engineering team lead manager and VP of engineering. The talks with the head of design and VP of engineering weren't technical, but the engineering team manager did ask me to whiteboard how I might implement a certain feature for a web app, from the backend models to the frontend, and asked how I might ensure fast performance. In the end, I didn't get an offer, but got good feedback on the areas I needed to improve in.
