Yes, a bunch of guys are already past that step.

Hint: think simple here, real simple

i am pretty sure it's not a valid data matrix code.

I stopped there as well... I tried two or three ideas but did not get nowhere

Too bad, maybe you should try again. We've made this step slightly easier now, with a hint or two added in the mix.

Thanks but no thanks! I am not really looking for job (I am actually quite far away from you and I also posted in this as I am also hiring). I am only curious on these types of challenges.

First two steps are good. The third one might be very easy but I found it very ambiguous. I suppose if you really need to find a job you will spend lots of time.
