Pergunta de entrevista da empresa Trackier

Build a k-v data store. But bro didn't even tell me which features to implement. He just said everything right from basic operations to indices and practically everything. All in 40 minutes which is unrealistic. Oh, clean code btw, wait it has to work perfectly too. I was given so much to code in just 40 mins and I bet the interviewer felt smart after asking me to code all of that in such a short span.
