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!
