Math exam, Written algorithm. The people are probably nice but when I walked in and asked are there offices or just open floor concept the interviewer manager replied "only managers have offices"- this cooled me off a lot. I didn't appreciate the comment and we didn't connect afterwards, I couldn't write anything on his coding test, I felt like frozen because I was disappointed. However I made a good connection and had a good discussion with the other manager who interviewed me next but because of the disastrous interview with the first one there was no continuation.
