So weird, get an iOS home work. It is the same as others -- 8 days an iOS app. Not easy, chat box and dynamic analysis dashboard with many details. It is not like an interview task, seems like part of the product of their company. ----- I google their website, NOTHING AT ALL only to find several demos. Oops, these are exactly what the tasks are: chat box, data chart..... Besides No their own app on the appstore. Thanks glassdoor and other people's interview feedback.

Had a brief 15min chat with one of the founders about the company and role. Afterwards they sent a lengthy take home assignment because of the requirements. Did receive some feedback on the assignment but ultimately they were moving forward with other candidates.
