I was contacted by a recruiter from TransferWise via LinkedIn. We had a ~45mins long discussion over phone where he introduced the company, the various engineering teams and openings and I was also asked about my background a little bit. He was very kind and gave a detailed, coherent description of the possibilities. He also called me once more before my onsite interview to make sure I had all the information I needed for preparation. Some days later there was an onsite interview with two software engineers that took 1.5hrs. The first half was a casual discussion mainly about my background going into details where the interviewers saw something interesting. In the second half I had to provide an implementation for a problem, I coded on a laptop (in Sublime Editor) with a shared screen so they could follow on TV. It was kind of a pair-programming, when I stuck they gave me hints, when I was ready with a sub-task they gave me a new question to extend the implementation, etc. Everyone was polite and kind, I felt that I didn't excel during the interview yet it was a good experience. Next week I got my feedback via email about that I have been declined and this was the only point that left me disappointed because the feedback was written in a pretty harsh way like "You have never used X!". I do accept that I didn't pass but the way the feedback was given makes me wondering how arrogant (?) the engineering culture can be there and doesn't make me to apply again in the future.
