Applied through referrals (position is actually postdoc fellow in machine learning). Talked to the manager and then had a phone screen with a senior researcher. Answered all questions and they seemed interested, but they are way too slow and if you don't follow up, they won't get back to you at all. The senior researcher seemed nice but mentioned doesn't have enough experience in machine learning. I don't know what's the point of interviewing postdoc applicants in the machine learning area and wasting their time, if you can't even find an appropriate interviewer who has enough expertise!

The whole interview process was very smooth. The interviewer started off with the basics, with him delving deeper into the topic, every time you answer correctly. He helped me too when I got stuck, so I was able to answer most of the questions I didn't know the answers of with the hints he provided. He summed up the interview by connecting all the dots at the end, and this gave a much clearer picture of the work I am supposed to do during the intern.
