Scanadu interview questions

First, I had phone interview followed by an on-site interview. They said that I will be considered further only if I pass the Farnswell-Munsell eye test. I cleared the test with really good score and after that was interviewed by 7 people. After 2 weeks, they tell me that they are not considering me. During the interview, they were very positive that you will be selected for sure because your skills and our requirement area match but it was saddening to see a negative response from them.
