JUMP Software Software Engineer interview questions

I was sent an email from a polymer email address that said I would receive instructions at 11 AM on a specific day. Take Home Assessment: 48 hours to complete after receiving instructions via email. Find a bug that involved multiple systems. I had to pay for two of them in order to get it to work properly (around $20.) I spent 12 straight hours on it on my day off and I was confident that I had solved it so I thought it was worth my time.
