Interview process:

• Recruiter screen
• Hiring manager round
• API design round with engineers.

For the hiring manager round, have scenarios in mind to answer "tell me about" type questions.

For the API design round: They give you poorly written code and you will have to improve it.

STRONG SUGGESTION: Complete the functional requirements first. Then focus on non-functional requirements. I messed up and spent a lot of time discussing improvements but ran out of time before completing the code. The recruiter mentioned this, and somehow I still didn't get the job.

Based on my conversations, it seems like a great place to work. I would interview again in the future.

API design.

Brush up on best practices.

Quickly get to writing code.

That's what they are looking for.

Keep it simple.
