Kickdrum Software Engineer interview questions

I applied for a Mobile developer post. The process includes 1 online coding round and 3 interviews. The online test contains 1 coding question and 1 database question. The 1st interview was about how we can design a chat application. Which tech stack we can use React Native vs ionic vs native, What all edge cases we need to consider and how we can deploy it to production based on different requirements such as region wise, device-specific, etc. The second interview was based more on Design. I was asked to design a database for a cricket score reporting app such as ESPN Cricinfo. It was a tough round and other questions in this round were more on architecture pattern MVP, MVC, etc. The 3rd and final round was with the director of engineering he mostly asked about my experience and the challenging things I have done in my past. Overall It was a good experience for me and I received the offer within 1 week of the interview.
