Interview
HR screen followed by a data project (1hr for doing project, 30min talk with a Data Scientist).
The interviewer was rude. She started the interview without introducing herself and asked question directly. The data project was a waste of time since the time was so limited and the problem was not clearly defined.

Interview
I was contacted quickly with a coding test, which I finished the same day, but the followup took a few weeks and the company consistently failed to respond/communicate despite trying to schedule and interview with me. Communication was sloppy and included lots of apologies for failing to respond promptly. Kensho is clearly disorganized and/or indifferent about my time, so I went with an offer somwhere else.
