The interview process began with an initial introductory call, followed by a technical phone screen. The hiring manager reached out directly, likely due to their current hiring surge.

The subsequent video interview consisted of four rounds over two days:

• Coding questions focused on general data structure and algorithm concepts.
• System design and technical depth were assessed in separate rounds.

Overall, the interview was not difficult. It's worth noting that pre-IPO companies like Rivian tend to offer more in Restricted Stock Units (RSUs) rather than base salary, which can make their total compensation less competitive.

Ultimately, I accepted an offer from another company and did not pursue further negotiation with Rivian.

Normal, medium-level coding questions, system design, etc.
