I have been using Codility primarily for interviewing candidates, and over the past three years, it has been an integral tool in my company's hiring process. I am happy with Codility and find the setup to be really simple, providing a smooth onboarding experience. One feature that stands out to me is the integrated development environment (IDE) on Codility, which I use extensively during interviews. Additionally, the integration with my reports is really useful, particularly for handling architecture-related questions, making Codility indispensable for efficiently conducting and managing technical interviews.

It's easy to use, and it also automatically detects any suspicious activities.

I used Codility for both as interviewer and interviewee. I like the part about that interviewer/interviewee can interact to each other real time through chats. Also, UI is neat and clean.
