The process begins with a recruiter call, followed by four LeetCode questions to be solved within 75 minutes. If you score perfectly or near perfectly, you will then interview with the CTO. Otherwise, you will be passed over.

A person who performs exceptionally well on LeetCode questions is not necessarily a senior engineer. They might simply be someone who has had significant spare time to study these types of problems, potentially memorizing solutions. Alternatively, they may have cheated during the coding challenge.

Instacart may wish to consider whether such "LeetCode stars" truly understand standard engineering principles like the Gang of Four, SOLID, or various testing methodologies.

Other interview reviews indicate that the company covers system design and other live coding challenges. This suggests the current culture may not be a good fit, unless one possesses a substantial ego and believes Instacart is comparable to FAANG companies.

Solve four questions in 75 minutes where perfect marks are expected.
