The recruiter was wonderful, from the 1st moment she let me feel like I could talk to her anytime. The interviews themselves were also great, LeetCode-ish but they all talked about Monday's product.

I didn't have any front-end experience so it surprised me that they let me get so far in the process, but in the end I couldn't get past the system design question. For someone who loves thinking about problems and has the required experience it shouldn't be too hard.

You need to design a feature from their product.
