You discover a lot when entering the job. It might be more true in tech than other jobs; god can the shock be awful, even after hours and hours of interviewing and asking questions. Someone quitting within weeks usually has a discussion with HR the first few days and stay there only long enough to hire someone else. That's I think a sign that the person has decent communication and just wont let you down at a random time because they're too pissed to do their job anymore. In this specific case, looking at the short job spree and the much longer tenure coming afterwards, I would not see it as a "throw the resume in the trash" kind of issue. Perhaps just bad interviewing skill (couldn't properly judge the company) and bad luck.
