As the interviewer admitted during the interview, the posted job descriptions are too vague and misleading; they write them up to sound fancy and exciting, not to be informative. I thought that the position involved x and y, but it turned out to be about something else. After we realized this, at which point I wasn't interested in the position anymore, the interviewer very abruptly ended the call. My overall experience and impression of this company is that it's a little amateur company trying to play grown-up. It's staffed by mostly very young people and hence lack professionalism, expertise, and respectability. I wouldn't recommend this company to any serious, ambitious job-seekers.
