First HR and Technical interview with a nice guy last about an hour, After a some days they invited me to second interview with two other (so serious) guys, last about an hour. I think they didn't even checkout my CV, many technical and organizational questions and they didn't send me an answer, once I reached out they told me to ask the recruiter to know the result!. It took me a week to be prepared and had 2 days off to participate in their interviews, so I expected to receive more respect.
