Even if you don't end up getting a job with the company, at least you will walk away with some operational experiences. Its amazing what you will pick up which will end up beneficial to you in the future.
A pilot with 200 hours who has had 1 year of baggage throwing/cleaning a/c, loading a/c will have a much better chance than someone with just a plain and simple 200 hours in gaining their first job.
And hey if you end up with a job at the company, its a bonus!!
Have fun
