Anywhere from three to five days per week, depending on several factors.
Since you have an active job that already burns a lot of calories, you might also want to consider a lower volume/higher intensity type of plan.
As was discussed in your previous thread, this will have much more to do with how you eat, rather than how you train.
In the last two weeks, how much bodyweight have you gained?
Fixed and clarified.
You can definitely gain straight-out "bodyweight" without getting stronger or improving in the gym. But progressing in the gym is one of the indicators that you're adding muscle, not just bodyfat. If the scale starts going up but you're not improving in most of your lifts, then your training probably needs tweaking.
