Trulia Data Scientist interview questions

There was first round of interview on the Machine Learning and they have asked me about CRF which I was working on. The interviewer is very popular and he has given lot of talks on Machine Learning. The only disappointment is they wanted someone to be with lots of experience.I had experience in Big data and Machine Learning and they wanted me to be interviewed for Data Engineer and they wanted some one to have 6 years of experience in JAVA.
