I had applied online and also contacted HR via email. HR replied, asking me to start the process.

Step 1: Take-home coding challenge

• The same two questions that Zillow asks everyone.

I completed this in 4 days.

Step 2: Phone interview

• General discussion on my previous projects.
• Find all pairs that add up to a certain value in an array.

Step 3: Skype interview

• General discussion on my previous projects.
• Find the lowest common ancestor.

Step 4: Onsite

• Four technical rounds on a whiteboard with different team members.
• The code that you write needs to be perfectly compilable.

Overall, my experience was great. HR was very quick to follow up, and I completed the process very fast. The office in downtown Seattle is amazing, with a great view from the 34th floor.

The interviews were very helpful, and the interviewers always had a happy demeanor.

A modified dynamic programming approach took me some time to figure out.
