First round was OA from CodeSignal.
Second round was conducted on Codesignal. Expect to read some code snippets and tell their complexity. Try to finish this part quickly as you will have an oop design question. The interviewer will try to keep you from straying away from the right solution. Pretty much like collaboration.
Onsite includes 3 rounds. 1x2-hour coding session, 2x45-minute system and design. For the 2-hour coding, the interviewer lets you ask questions and then logs out so you can work alone for 70 minutes. After that, he comes back to go over your implementation and asks questions. For the system round, expect some lc coding and oop design. For the design, be ready to communicate clearly and think out loud. I actually had a lot of fun and learned something new in this round. This round was very practical.
Overall, people were really engaging and smart.
The onsite has built-in 15-minute breaks between rounds. Also, they give you a 45-minute session to talk to an engineer to learn more about the company.
My recruiter was willing to give me some high-level feedback, which is something not many companies do.
I would say that I had a pretty good experience with Asana.
