Was contacted by the HR team. Had a good first screening and then I was given a case study to solve. I solved and submitted my solution. My solution was accepted.

However, after going through the case study they rejected me. The technical guy who went over my case study somehow didn't like my solution even though it was a normal one. He also mentioned that a lot of people didn't even reach a solution. Even though I did, it was somehow not enough.

He dug way too deep and I answered all of his questions as well as justifying my decisions. Either it was not enough or he was just having a bad day. He also had a negative attitude all along during the interview.

Create a deep learning network that sums up single digits and outputs the sum. The summation had to be done by the network using the MNIST digits dataset.
