It opens an online editor that the interviewers can consult to check how you move through the challenge. The choice of preferred language included Java, Python, and C++.

If onsite, you are immediately told if you proceed to the next stage, where you'll interview with 2 software engineers.

Second interview: start by commenting on how you approached the code challenge, followed by a battery of technical questions + behavioral.
