Appspace Software Engineer - Platform interview questions

I was contacted by Igloo through Linkedin asking for a 30 minutes phone call. The call is pretty straight forward and they ask about what you have done and experience, in addition to that they let you ask questions. The very next day I got an email with a link to a code challenge, that I was supposed to review and send them an estimate when I will complete it. A week after sending them my response they booked in office 1-hour interview with 5 people - (2 dev, 2 dev manager, 1 director). In this interview, they asked about my background, what I have done that I am proud of, a couple of questions regarding agile, reviewed my code challenge and made comments. A week after I got an email to say I am not what they are looking for.
