Experian Data Science interview questions

ML problem and probabilities. The interviewer were nice and patient. He gave hints and was showing engagement. He did mention possibility of overworking. Yet the interview process was poor. Interviewed then never gotten a reply. Sent multiple emails after a couple weeks and still got not reply whatsoever. Just poor execution.

The phone interview was carried out by one of their principle scientists, and lasted for about an hour. The interviewer was very friendly. After brief introductions, there are a list of questions asked, including coding, probability, linear algebra, numerical analysis. The interview was mainly focused on skills and knowledge, not so much about behavioral. Not your regular phone interview.
