Post office or B.F.I Jobs?

How easy is it to get a job at the Post office after taking the Civil Service Test? Also, is it good to try to get a job at B.F.I Waste and Recycling?

As for the Post Office, you will be on a hiring list. The higher your mark the better your chance. But remember that if a veteran has the same mark as you they get a veteran's preference depending on their status. (either 5 or 10 point add on)
It can take months or a couple of years to be called. Contrary to another answer, all new hires are Part Time Flexible employees. That does not mean you will work less than 40 hours. In my case in the 2 years that I was a PTF I always worked at least 40 hours a week, and in busy times of the year I worked 60 hours a week. There is an 89 day probationary period. Once you get past that, you will be in for good (or bad).

At the start you get 13 sick days annuallly, and 13 Vacation (annual leave) days annually, though the vacation days probably will NOT be in July or August. You can save your sick and annual leave from year to year.

The PO pays a majority of your health benefits, there is good job security if you're not a knucklehead.

Myself I would try BFI more chance to advance.

Well: according to " U.S Government jobs when you apply
for Post office an test is required called Employee's
Civil Service & must pass that yes also great pay/benifits
if yourself gets hired full time after 6 months of Basic
Training first !"
