Working at an Amazon Warehouse is okay if that's all you can find as a job however if you can find a job somewhere else in a different warehouse then I would advise you to do that.
I worked at an Amazon Warehouse for 2 years before I quit after finding another better job.
At the Amazon warehouse you must be fast and not too slow. Going too slow will get your fired.
It's also hard on the legs and feet and you must continue moving around in the warehouse until break time.
You only get two 15 minute breaks and a 30 min lunch break and the break time is counted from when you last scanned an item, So a lot of the time you would have 5 minutes of walking time to and from the break room and only 5 minutes of actually sitting.
Working at Amazon Sucks and I wouldn't recommend it to anyone unless that's the only job they can find for now.
If you do get hired at Amazon I highly advise you to continue searching for better jobs while you work at Amazon Warehouse because it's not a good job to stay in your whole life.
