I received an email from recruiter that they found my resume and want to interview me. After a 10 minutes phone call, they set a technical interview with 2 data scientists. Both interviewer called me at the same time. It seemed they did not coordinate with each other. Then one of them start the interview and explained about their projects. Then I briefly described my projects and skills. Then he started to ask different machine learning questions which were easy for me and I connected my answers to the real projects I did before. After 10 data science questions he asked one algorithm question about arrays. I gave 3 solutions all of them was correct. Then He asked for an o(n) solution that it did not come to my mind at that moment. The interviewer was very nice.
