Chime

Typical interview loop

How Chime usually runs it for applied AI and LLM engineer roles.

1. 1

   Recruiter screen

   Focus: Background, fintech motivation

   A half-hour call on your ML background, why fintech and Chime's mission, and how the process will run.

2. 2

   Technical screen

   Focus: Practical coding, thought process

   An hour of live collaborative coding with an engineer, where your reasoning counts as much as the answer; ML roles may get ML fundamentals or a take-home instead.

3. 3

   ML deep dive

   Focus: Model selection, deployment experience

   A walk through your past ML projects covering model choice, trade-offs and how you took models to production.

4. 4

   Onsite: coding and system design

   Focus: Coding, reliable system design

   A four-to-five-hour virtual day with coding rounds and a system design round, often around money movement or end-to-end ML systems, with attention to reliability and testing.

5. 5

   Onsite: product and manager rounds

   Focus: Collaboration, member focus

   A cross-functional round on working with product partners and an engineering-manager deep dive into your experience.
