Job hopping happens all the time, but I suggest that you think about why you want to quit before you quit. Don’t follow suit. Seeing that all of your colleagues have left, and you start the interview blindly (I didn’t prepare enough during the period), is it because of technical reasons (affecting your own development, deviating from your planned trajectory) or money Less, not taken seriously.
