Gave a take-home project to implement weather app. Given an API (Years old with API deprecated way back so you have to find a workaround). Make a call to weather API and show the data for the current location. Got back to me in 2 weeks with rejection with a rude feedback and weird suggestion how they wanted me to implement things. For reference, I submitted similar architecture for 5 other companies and they all gave a big thumbs up to me, but Klarna seemed to be an outlier so I don't feel bad about rejection. Suggestion: Try to do things MVC way since team seemed to be interested that way. If you want to go to better companies, use this company as a launchpad since current employees don't seem to be happy anyway
