It was a long interview process, but interesting because of the variety of rounds. While I am not sure how each round was weighted toward their final decision, I personally think it is better for candidates to have more chances to prove themselves.

I interviewed in NYC and always received prompt feedback, never having to wait long to know where I was in the process.

Rounds:

• Initial chat with recruiter to gauge interests, reasons, and fit.
• Cognitive Aptitude Test - the timed test covered verbal, math, logical, and spatial reasoning.
• Take-Home Coding Project - like most places that give these out, the expectation was for both quality and completeness. It had to work, have tests, a correct build file, and a good README.
• Coding Round - I didn't get a standard LeetCode question, but preparation on LeetCode patterns helped with problem-solving regardless.
• System Design Interview - with a rather deep dive into my own experience, especially with cloud technologies.
• Interview with CTO - again with a deep dive into my experience and skills, with insights into the company.
• Catch-up with the recruiter to get feedback and advice on how to approach the final round.
• "Bar Raiser" - which is a final round with a senior leader from a different department. This wasn't technical but had a heavy cultural fit focus.

Project: Implement a functional API in any language to satisfy the requirements, with a detailed explanation of your choices.
