Hi! Unfortunately, I think you are likely mistaking us for another company called Cord in London (perhaps cord.co or cord.tech). We do not use take-home challenges, don't ask these questions in interviews, and this isn't our interviewing process. I'm sorry you've had a negative experience and hopefully by reporting this to the correct company they can adjust. We'd be very happy for you to apply and witness our process if you like, at https://cord.com/jobs/
