Booking.com Data Scientist In Natural Language Processing interview questions

I have applied at booking.com couple of times and the experience has been pathetic. First time, the interview ended after a phone call and second time after a written test about machine learning. What I find bad about this particular interview is that no reason whatsoever is given for rejection from a test like a written data scientist test. I mean, I was pretty sure I got many answers right. Could they at least share my score and if my score was good and they still rejected, then why give the test in first place? It would be better if they start and then go all the way or not start altogether!
