After a first interview with a quick talk about the company's objectives, there was a second short technical interview. Interviewers were very professional and cordial. The technical interview was too simple and could hardly evaluate a potential employee's contribution, which is why the final decision to not continue the process was puzzling. The feedback was also not good. I advise you to question the interviewee about actually important application development concepts instead of expecting memorization of syntax in a non-IDE environment.
