Kensho Technologies Software Engineer(Internship) interview questions

They designed the questions themselves and the interviewers are pretty nice guiding you through the interview. I feel good going all the way through the final and was told will be informed with the result soon and get feedback on phone call. But until quite a few days later, only one rejection email come into my mailbox without any feedback and then the recruiter just disappeared and never replied. I got quite a few better offers so I don't really care about the result, but just feel not respected as I have spent so much time interviewing this company and they are not even willing to share the feedback.

Standard DS & A questions for the coding assessment. For the phone interview, I was given two functions that were not well defined, then asked to implement a "data structure or anything" to make the functions work. I was allowed to write in any language, so I chose Java. However, the interviewer did not know Java very well so I had to set up the classes and main functions myself. I talked through my thoughts and managed to run the codes but the question was rather confusing and not properly set up and the interviewer was not entirely helpful or clear about what they wanted me to do.
