I applied online and after few days I received an e-mail from the recruiter to fix a skype interview. The interview was about 20 minutes and asked about my lasts experiences. After that, I had an one hour interview with a software engineer. He asked general questions about data structures (difference between array and list, how hashmap works, etc.). Finally he gave me one easy problem to solve on shared screen. I answered well to most of the questions and solved the problem, but I received a reject with the feedback that "I am not yet at the level required on the Computer Science side". I have to mention that I have a PhD in Computer Science. They don't care about your studies or experience, just to answer perfect to questions.
