They have four whiteboard interviews, with minimal coding (aside from function prototyping), which lets you focus on algorithms and problem-solving.

Additionally, they have a one-hour coding session where you write code alone to solve some short coding exercises. You then review these exercises with an interviewer.

They also conduct a tech demo, showcasing the Asana product so you can gain perspective on using Asana as a team member.

They really focus on your reasoning and problem-solving skills, and are willing to provide you with the information or hints you need. It's much more conversational than at some other places. I really enjoyed the process.

Questions included various algorithmic/data-structure problems, as well as a systems design exercise (e.g., web server setup, database setup, etc.).
