The process was very fast: an introductory call and an on-site exam. The only problem I found was that the interviewer supposedly gave me an hour to take the test. However, he was already with me after 25-30 minutes and asked me how I would answer the questions I missed. Each question had difficulty noted, and precisely, the missing ones went from ¨ difficult ¨ to "very difficult." Answering a "very difficult" question without considering it first is tricky. In the end, I solved it, but my interviewer used this argument to stop my selection process, saying that someone else had done it the first time. I wonder if this person had enough time to think about it in advance or if it was just a "reason" to be able to reject or stop the process in case he preferred someone else.
