Zalando Senior React Native Developer interview questions

1 HR 1 Hiring manager 3 rounds - coding, general technical interview, System design. Coding round - was asked to make a webpage - asking to code a webpage for a react-native-mobile role is just beyond me. System design - good, asked how to make a brownfield app to greenfield General Tech - Again -was taking by a web engineer and was about Web tech, how a url works? How would u optimise webpage performance? i tried to answer to my best of abilities, got the offer, then got lowballed by HR, was offered MID level, even after pointing out flaws in their interview questions. - i wish them all the best, and i wish any one seeking this role to prepare for WEB is they want to get in to the company.
