Deckard Technologies interview questions

One hackerrank challenge then two interviews. First interview was a basic skills and culture chat with one team member. Second interview was with two other team members, being quizzed on machine learning concepts, terminology and techniques.

I had one hackerrank and one Interview round, (Very nice understanding person) Interview went well (one hour time for interview) They said you will be having one round with Management but two weeks later, I got rejected
