After only three weeks from the day I left my previous job I have been invited by this company to join their team. I accepted the invitation right away, but now three other weeks have passed and, for a number of reasons, I don't feel neither comfortable nor satisfied enough with my choice. I would like to start looking for a new job again, but I don't know whether it will be beneficial or not to include this 3-week-long experience in my CV.
The truth is that in these three weeks I learned a lot of new things about Java (which is most certainly what I will be applying for anywhere else), but I am afraid that "stating" in the CV that I want to leave a company I joined just the other day will give a bad image about myself.
How should I deal with my current position in my CV?
