Loop Earplugs interview questions

The interview itself was nice, good questions were asked, but the assigment for the last interview is VERY demanding, feels like speculative work. It's a combination of 5 to 6 different tasks that would take more than a week of full time work on them.

Expose a business case to solve a real life problem with hearing protection. Prepare a slide deck for the interview and present it. Follow-up technical questions will be asked. Additional interview with future colleagues can be done.
