Our team (devs and QAs) have been doing a series of overtime work.

So, the company has provided us a place to sleep. Everyday, we would go to work at 10AM and then return to our place to rest at 12 midnight (sometimes at 2AM).

We've been doing this for a week now and we'll resume again tomorrow.

I already feel exhausted, and I was thinking of resigning after all of this mess was over.

However, I am having second thoughts. Since this is my first job, I have no point of comparison.

Perhaps a series of overtime like this one is normal? Is this type of work environment to be expected when being a developer? Or am I selling my self short and there are better options out there? What do you devs think?
