I applied online. The process took two weeks.

There were two rounds: one technical and one behavioral.

• The technical round was with a current engineer at WS, and it was not a traditional LeetCode-style problem. I was greeted with a problem that required me to implement numerous functions and classes that are a part of the stock trading system in one hour. I was free to choose my programming language, though.
• In the behavioral round, I met with a few engineering managers, and those whom I met with were the ones who would choose whether or not I would be on their team. There were standard behavioral questions, describing your tech stack, and experiences, etc.

The process included the following:

• Implement a simple stock buy/sell system.
• Discuss what frameworks you have used.
• Tell about your past projects.
