The entire process took about a month. The first step was a Java coding project, straightforward question and gives an opportunity to use their B2 product. Once the project was reviewed I moved on to a technical interview with a senior engineer via coderpad. They are mostly interested in seeing how you code and think through a problem rather than focusing on correctness. This session was also very collaborative. After this I moved on to an entire day of interviews and met with several engineers and managers. The types of interviews will vary based on the role, but you can expect a mix of behavioral and coding interviews. Everyone I encountered was very friendly. I recommend looking through their blog to learn more about the company and the interview process.
